5 Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals or any other substance hazardous to health must be decontaminated before it is returned to Watson-Marlow or its distributor.

A certificate included at the rear of these operating instructions, or signed statement, must be attached to the outside of the shipping carton. This certificate is required even if the pump is unused.

If the pump has been used, the fluids that have been in contact with the pump and the cleaning procedure must be specified along with a statement that the equipment has been decontaminated.

6 Peristaltic pumps - an overview

Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps can operate dry without risk.

How they work

A compressible tube is squeezed between a roller and a track along an arc of a circle, creating a seal at the point of contact. As the roller advances along the tube, the seal also advances. After the roller has passed, the tube returns to its original shape, creating a partial vacuum which is filled by fluid drawn from the inlet port.

Before the roller reaches the end of the track, a second roller compresses the tube at the start of the track, isolating a packet of fluid between the compression points. As the first roller leaves the track, the second continues to advance, expelling the packet of fluid through the pump's discharge port. At the same time, a new partial vacuum is created behind the second roller into which more fluid is drawn from the inlet port.

Backflow and siphoning do not occur, and the pump effectively seals the tube when it is inactive. No valves are needed.

The principle may be demonstrated by squeezing a soft tube between thumb and finger and sliding it along: fluid is expelled from one end of the tube while more is drawn in at the other.

Animal digestive tracts function in a similar way.

Suitable applications

Peristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. They are especially useful for pumping operations where hygiene is important.

Peristaltic pumps operate on the positive displacement principle. They are particularly suitable for metering, dosing and dispensing applications. Pumps are easy to install, simple to operate and inexpensive to maintain.

9 Good pump installation practice

9.1 General recommendations

A correctly engineered installation will promote long tube life. Site the pump on a flat, horizontal, rigid surface, free from excessive vibration, to ensure correct lubrication of the gearbox. Allow a free flow of air around the pump to ensure that heat can be dissipated. Ensure that the ambient temperature around the pump does not exceed 40C.

The STOP key on the keypad will always stop the pump. However, it is recommended that a suitable local emergency stop device is fitted into the mains supply to the pump.

Do not stack pumps more than three high. When pumps are stacked, ensure that the ambient temperature around all the pumps in the stack does not exceed 40C.

The pump may be set up so that the direction of rotor rotation is clockwise or counter-clockwise, whichever is convenient. Please note, however, that with a 501RL pumphead tube life will be greater if the rotor rotates clockwise; and that performance against pressure will be maximised if the rotor rotates counter-clockwise.

Peristaltic pumps are self-priming and self-sealing against backflow. No valves are required in inlet or discharge lines. Valves in the process flow must be opened before the pump operates. Users are advised to fit a pressure relief device between the pump and any valve on the discharge side of the pump to protect against damage caused by accidental operation with the discharge valve closed.

9.2 Do's and do not's

Do not build a pump into a tight location without adequate airflow around the pump.

Do keep delivery and suction tubes as short and direct as possible - though ideally not shorter than 1m - and follow the straightest route. Use bends of large radius: at least four times the tubing diameter. Ensure that connecting pipework and fittings are suitably rated to handle the predicted pipeline pressure. Avoid pipe reducers and lengths of smaller bore tubing than the pumphead section, particularly in pipelines on the suction side. Any valves in the pipeline (not usually needed with a self-priming peristaltic pump) must not restrict the flow. Any valves in the flow line must be open when the pump is running.

Do use suction and delivery pipes equal to or larger than the bore of the tube in the pumphead. When pumping viscous fluids use pipe runs with a bore several times larger than the pump tube.

Do ensure that on longer tube runs at least 1m of smooth bore flexible tubing is connected to the inlet and discharge port of the pumphead to help to minimise impulse losses and pulsation in the pipeline. This is especially important with viscous fluids and when connecting to rigid pipework.

Do site the pump at or just below the level of the fluid to be pumped if possible. This will ensure flooded suction and maximum pumping efficiency.

Do keep the pumphead track and all moving parts clean and free from contamination and debris.

Do run at slow speed when pumping viscous fluids. Flooded suction will enhance pumping performance in all cases, particularly for materials of a viscous nature.

Do re-calibrate after changing pump tubes, fluid, or any connecting pipework. It is also recommended that the pump is re-calibrated periodically to maintain accuracy.

IP31 models may be wiped down with a wet cloth, but should not be hosed or immersed.

When using Marprene or Bioprene continuous tubing, do re-tension the tube after the first 30 minutes of running.

Tube selection: The chemical compatibility lists published in Watson-Marlow publications are guides. If in doubt about the compatibility of a tube material and the duty fluid, request a Watson-Marlow tube sample card for immersion trials.

10 Care and maintenance

The pump is sealed to IP31 and is suitable for wipe-down cleaning. Do not use solvents, mechanical scourers, strong organic acids, or alkali-based cleaning solutions.

Remove any tubing, detach the pumphead, and wash the pumphead thoroughly with a mild solution of detergent in water.

Check moving parts of the rotor from time to time for freedom of movement. Lubricate pivot points and rollers occasionally with Teflon lubricating oil.

The pump has a good, broad chemical resistance to inorganic acids, saline solutions, alkalis, some hydrocarbons and a large number of oils and greases. It is suitable for wipe-down but not for long-term contact with alcohols. The case may be damaged by contact with strong acids or strong solvents

There are no user-serviceable parts inside the pump. The unit should be returned to Watson-Marlow or its appointed agents or distributors for service.

11 Connecting this product to a power supply

We recommend using commercially available supply voltage surge suppression where there is excessive electrical noise.

The voltage selector is located at the rear of the pump. Set the voltage selector to 115V for 100-120V 50/60Hz supplies or 230V for 200-240V 50/60Hz supplies. Always check the voltage selector switch before connecting the mains supply.
Make suitable connection to a single-phase mains electricity supply, using the supplied power cable with moulded plug. The cable uses the colour code:

220-240V: live: brown; neutral: blue; earth: green/yellow.
110-120V: live: black; neutral: white; earth: green.

Input line fusing: type T1,0A time-delayed fuse, located in the combined inlet socket and fuseholder at the rear of the pump.

Power interruption: This pump has an auto-restart feature which, when active, will restore the pump to the operating state it was in when power was lost. See Auto-restart.

Stop / start power cycles: Do not power up/power down for more than 10 starts per hour, whether manually or by means of the auto-restart facility.

12 Start-up check list

Note: See also Tube loading, 313 and 314 and Tube loading, 501RL.

Ensure that proper connections are achieved between the pump tube and suction and discharge piping.
Ensure proper connection has been made to a suitable power supply.
Ensure that the recommendations in the section on Good pump installation practice are followed.

13 Switching the pump on for the first time

Note: This manual uses bold type to highlight the active option in menu screens: "English" in the first screen represented here. The active option appears on the pump display in inverse text.

16.2 Manual control

All settings and functions of the pump in manual mode are set and controlled by means of key-presses. The currently selected rotation direction is indicated on the display by a clockwise or counter-clockwise segmented arrow. If an exclamation mark ( ! ) shows, it indicates that Auto-restart is on.

Note: A number of the controls listed below are shortcuts to commands which are also available through the main menu. See Main menu.

A brief single press on each key triggers a beep sound (if enabled - see Keypress combinations, below) and causes the pump to function as follows:

START: starts the pump at the speed and in the direction shown on the display. The rotation symbol will become animated to confirm that the pump is operating. We recommend that the speed is reduced to a minimum before starting the pump.
STOP: has no effect if the pump is not running. If the pump is running, pressing STOP stops the pump. The display continues to show the previous speed and direction. The pump returns to this speed and direction when the START key is pressed again.
UP: increases the speed shown on the display in minimum steps of 1 rpm (unless the speed displayed is already the maximum speed). If the pump is then started by pressing the START key, it operates at the new speed. If the pump is running when UP in pressed, the change takes effect immediately.
DOWN: decreases the speed shown on the display in minimum steps of 1 rpm. If the pump is then started by pressing the START key, it operates at the new speed. The minimum speed possible is 1 rpm (low speed model) or 2 rpm (high speed model). If the pump is running when DOWN is pressed, the change takes effect immediately.
Note: You can reduce the pump speed to 0 rpm by a further press on the DOWN key. The pump is still in the running state and the rotation symbol will continue to move. Press the UP key to return the pump to the minimum speed.
DIRECTION: toggles the direction of rotation shown on the display. If the pump is then started by pressing the START key, it rotates in the new direction. If the pump is running when DIRECTION is pressed, the change takes effect immediately.
RETURN: stops the pump (if it is running) and displays the main menu.

Keypress combinations cause the pump to function as follows:

UP and DIRECTION on power-up: toggles the keypad beep on and off.
START on power-up: switches on the Auto-restart facility. See Auto-restart.
STOP on power-up: switches off the Auto-restart facility. See Auto-restart.

Start the pump with the START key.
The rotation symbol moves to confirm that the pump is operating. The symbol is static when the pump is stopped.
Stop the pump with the STOP key. The pump stops immediately.
The display continues to show the previous speed and direction. The pump returns to this speed when the START key is pressed again.
You can reduce the pump speed to 0 rpm with the DOWN key. The pump is still in the running state and the rotation symbol continues to move. Press the UP key to return the pump to the minimum speed.

Press the RETURN key to return to the main menu. If the pump is operating it stops, and the main menu is displayed.

16.3 Calibration procedure

To dispense the correct amount of fluid the pump must know which pumphead is fitted and the tube size in the pumphead. You may also measure the flow from the pump and enter this value for the most accurate calibration.

Use the UP and DOWN keys to select Calibrate from the main menu. Press RETURN.
The pump shows the stored values of pumphead, tube size, and present flow rate in ml per minute. Example figures are shown here.
If the pumphead and tube information is correct, select Accept and press RETURN. The pump briefly displays a summary of the current speed and flow settings, and the main menu.
If the pumphead and tube information is wrong use the UP and DOWN keys to select Change and press RETURN.
- The display lists pumphead options. Use the UP and DOWN keys to select the correct one and press RETURN.
- The display lists the tube sizes. Use the UP and DOWN keys to select the correct size and press RETURN. The display asks the user if he wishes to run a calibration dose.

The display asks the user if he wishes to run a calibration dose. To obtain the most precise calibration, select Yes. Select No if you wish to use the pre-programmed flow data and return to the main menu via a summary of the current speed and flow settings. Press RETURN.
If you choose to run a calibration dose, the pump displays its current direction and rotation speed. You may change pump rotation direction and speed using the DIRECTION and UP and DOWN keys.
Put a measuring container at the pump outlet. Press START. The pump runs for 4 minutes, displaying an information screen for 15 seconds and a further information screen for the rest of the 4 minutes. You may stop the calibration dose at any time with the STOP key - but allow the pump to run as long as possible to obtain the most accurate calibration. A minimum of 15 seconds is recommended.
Measure the quantity of fluid dispensed. The measurements must be in millilitres for calibration and dosing. The pump displays its calculated dose volume, based on previous calibration data. Use the UP and DOWN keys to adjust this reading to match the measured volume. Press RETURN. The pump displays the new head, tube and flow settings, and redisplays the main menu. Example figures are shown here.

It is also possible to re-calibrate the pump during a batch run. (See Dose.) Re-calibration allows fine tuning of basic calibration (see Re-calibration in the Dose section).

If a re-calibration differs by more than 25% from the original calibration, the re-calibration value will be ignored. Another full calibration is required to change a dose size by more than 25%.

16.4 Dose

The Dose facility programs the pump to dispense measured volumes of fluid. These can be individual doses, a batch of doses delivered singly, or a batch of doses delivered at timed intervals. A dose, or batch of doses, can be controlled by the pump, by pressing the START key, or by pressing an optional remote-control foot or hand switch or by an external logic signal.

You can start pumping immediately using the settings chosen for the previous batch; or you can alter one or more of the settings before starting to pump.

To start pumping immediately:

Use the UP and DOWN keys to select Dose from the main menu. Press RETURN. The pump displays the dose size, dosing interval and the number of doses and waits for the START key to be pressed.
When the START key is pressed, the pump offers the user the opportunity to prime the pump. To do so, press and hold the START key. The pump operates continuously at maximum speed until the START key is released.
When priming is complete, or if no priming is required, press RETURN. The pump displays the dose size and the number of doses and waits for the START key to be pressed to start the batch.

To alter the batch settings before starting pumping:

Use the UP and DOWN keys to select Dose from the main menu. Press RETURN.

The pump displays the first three of the eight parameters which may be set for the next dosing session: dose volume, dosing interval and number of doses.

The Dose menu occupies three screens.

To move from one screen to subsequent screens, repeatedly press DOWN. Each item is highlighted in turn until the last item on the screen is highlighted. A further press on the DOWN key displays the next screen of the menu, with the first item highlighted.
Follow the reverse procedure using the UP key to move to an item on a previous screen of the menu.

Make a selection using the UP or DOWN keys and press ENTER to confirm your choice. The values shown are those set for the last dosing session. As each parameter of the eight is highlighted, you may accept or change its value.

If it is correct, do nothing. UP and DOWN will highlight the next parameter.
If you wish to change it, press RETURN. Use the UP and DOWN keys to alter the value. When the value is correct, press RETURN.
At any time during the dose setup sequence described below the user may press START and the pump displays the priming screen and may be operated according to the parameters in force. If the next batch requires only the dose size to be changed from the last batch, for example, change it and press START, ignoring the other seven parameters.

In this programming area, pressing STOP while setting up dosing parameters returns the value being changed to its original setting, allowing the user to start again.

Dose volume

Use the UP and DOWN keys to highlight the volume line of the display (the top line, first screen).
If the dose volume displayed is correct, do nothing. UP and DOWN highlight the next or previous parameter.
If you wish to change the dose volume, press RETURN and use the UP and DOWN keys to scroll the display to the required dose volume. Example figures are shown here. To quickly return to the starting value, press STOP. When the dose volume is correct, press RETURN. The first screen of the dose menu is redisplayed with the new dose size. If you wish to change other parameters, use the UP and DOWN keys to highlight each as required.

Note: The dose size must use more than two complete revolutions of the pumphead. To obtain best accuracy the dose size should use more than five revolutions. Where the dose size uses less than five revolutions, the pump may warn that a smaller tube size is required. If you do not change the tube size, the pump may proceed with your selected dose size but accuracy may be reduced. If the dose is smaller than the two revolution minimum, the pump displays a warning and does not allow you to proceed. If you wish to proceed with the dose size, you must perform a new pump calibration using a smaller tube size. (See Calibration).

Dose interval

Use the UP and DOWN keys to highlight the dose interval line of the display (the second line, first screen). The display shows the previously set time interval between doses in seconds.
Note: If the time is set to zero, the pump waits for a start signal from the START key, or from an optional external control switch or logic signal, before proceeding with each dose. If the time interval is greater than zero, the pump proceeds through the sequence of doses at the programmed time interval.
If the interval displayed is correct, do nothing. UP and DOWN highlight the next or previous parameter.
If you wish to change the interval between doses, press RETURN and use the UP and DOWN keys to scroll the display to the required interval. Example figures are shown here. To quickly return to the starting value, press STOP. When the dose interval is correct, press RETURN. The first screen of the dose menu is redisplayed with the new dose interval. If you wish to change other parameters, use the UP and DOWN keys to highlight each as required.

Number of doses

Use the UP and DOWN keys to highlight the dose number line of the display (the third line, first screen). The display shows the previously set number of doses.
If the number displayed is correct, do nothing. UP and DOWN highlight the next or previous parameter.
If you wish to change the number of doses, press RETURN and use the UP and DOWN keys to scroll the display to the required number. Example figures are shown here. To quickly return to the starting value, press STOP. When the number is correct, press RETURN. The first screen of the dose menu is redisplayed with the new number of doses. If you wish to change other parameters, use the UP and DOWN keys to highlight each as required.

Note: If the number of doses is set to 1, the pump waits for a press on START for each dose, and the display during dosing increments with each dose. If the number of doses is set to greater than 1, the display decrements with each dose until it reads zero and the batch is complete.

Pump speed

Use the UP and DOWN keys to highlight the speed line of the display (the first line, second screen). The display shows the previously set pump speed.
If the speed displayed is correct, do nothing. UP and DOWN will highlight the next or previous parameter.
If you wish to change the speed, press RETURN and use the UP and DOWN keys to scroll the display to the required speed, up to a maximum of 300 rpm (low-speed model or high-speed model fitted with a 314 pumphead) or 400 rpm (high-speed model fitted with a 313 pumphead). Example figures are shown here. To quickly return to the starting value, press STOP. When the speed is correct, press RETURN. The second screen of the dose menu is redisplayed with the new pump speed. If you wish to change other parameters, use the UP and DOWN keys to highlight each as required.

If you wish to change other parameters, use the UP and DOWN keys to highlight each as required.

Drip

The pump can be set to reverse briefly at the end of each dose to prevent drips.

Use the UP and DOWN keys to highlight the drip line of the display (the second line, third screen). The display shows the drip setting of the last dosing session: from 0 to 1.0: zero to one revolution at one-tenth of a revolution intervals.
If the setting displayed is correct, do nothing. UP and DOWN will highlight the next or previous parameter.
If you wish to change the setting, press RETURN and use the UP and DOWN keys to increase or decrease drip reversal: zero revolutions to 1 revolution at 0.1 revolution intervals. An example is shown here. To quickly return to the starting value, press STOP. Press RETURN when correct. The third screen of the dose menu is redisplayed with the new drip setting. If you wish to change other parameters, use the UP and DOWN keys to highlight each as required.

Proceed

The third line of the third screen presents the option Proceed.

If you wish to begin the dosing session, use the UP or DOWN keys to highlight Proceed and press RETURN. The pump offers the user the opportunity to prime the pump. To do so, press and hold the START key. The pump operates continuously at maximum speed until the START key is released. When priming is complete, or if no priming is required, press RETURN. The pump displays the dose size and the number of doses and waits for the START key to be pressed.
If you wish to review or change the parameters for the next batch, press STOP twice and use the UP and DOWN keys to move back up through the list of parameters.

Single dose dispensing

When START is pressed, the pump performs a dosing batch according to the parameters set.

If the batch is set to perform one dose, as in the example shown here, the pump stops when that dose has been dispensed and waits for a further press on the START key. As each dose is dispensed, the display increments, recording the number of doses dispensed so far.

Note: To dispense a batch of one dose and set the pump to count the doses/batches, check that the dose interval is set to zero seconds. If an interval is set, the pump will still dispense batches of one dose, but will not increment its display to show how many doses/batches have been dispensed.

Batch dispensing

If the batch is set to perform more than one dose with a set interval between doses, the pump operates until all the batch's doses have been dispensed. The display decrements as each dose is dispensed, showing the number of doses still to be dispensed. During the intervals between doses - 3 seconds in the example shown - the time elapsing is counted down to show how much time is left before the next dose will start.

If the interval is set to zero seconds, the batch can be dispensed in individually triggered doses by repeated presses on the START key. The display decrements as each dose is dispensed, showing the number of doses still to be dispensed.

When the batch is complete, the pump displays a screen summarising the batch, and offering two choices: start the batch again or return to the menu screen, where batch setting changes can be made.

Use the UP and DOWN keys to highlight Start or Menu and press RETURN.
If you select Start, the pump displays the dose size and the number of doses and waits for the START key to be pressed to begin a repeat batch.
Alternatively ...
Just press START.
Note: When a batch is repeated, no opportunity is offered to prime the pump. If you wish to re-prime the pump, return to the main menu and re-enter the dosing menu as if it were a new batch.
If you select Menu, the pump displays the main menu. See Main menu.

Batch pause

You can interrupt a batch at any time by pressing STOP. The pump stops and offers four choices: Unpause: continue the dose sequence from where it was stopped; Restart: start the dose or the batch from the beginning; re-calibrate: re-calibrate the pump; and Exit: abandon the batch and return to the main menu.

Use the UP and DOWN keys to make a selection. Press RETURN to confirm.
Unpause: If you choose Unpause the pump finishes dispensing the current dose and completes the batch.
Restart: If you choose Restart the pump displays the number of doses in the batch and the number which have been completed. It offers two choices: restart the interrupted dose or restart the batch. Use the UP and DOWN keys to make a selection. Press RETURN to confirm.
- Select Restart dose and the pump re-dispenses the interrupted dose and resumes the batch where it was interrupted - as in the example shown above.
- Select Restart batch to command the pump to display the size and number of doses in the batch, as in the example above, and wait for the START key to be pressed to restart the batch.
Re-calibrate: (Note: In this manual, re-calibrate means adjust the full calibration previously performed. It is not possible at this point to perform a fresh full calibration. To do so return to the main menu. See Calibration.) If you choose re-calibrate you can check a recent dose and adjust the dose size (within a range of ±25%) for the remainder of the batch.
The display shows the volume of fluid it believes it has dispensed in each dose.
Measure the volume of fluid dispensed in a recent dose.
- If the pump's display is correct, press RETURN.
- If the pump's display is incorrect, use the UP and DOWN keys to adjust the volume displayed to match the measured quantity of fluid. Press RETURN to leave the re-calibration sequence.
- If the volume adjustment needed is greater than 25%, it is likely that the original calibration is incorrect. The pump displays a warning and resets to the original calibration value. You must perform a new pump calibration. Press RETURN to leave the re-calibration sequence.
- The pump redisplays the four choices: Unpause; Restart; re-calibrate; and Exit.
- Use the UP and DOWN keys to make a selection. Press RETURN to confirm.
- If you choose Unpause or Restart the pump operates as described above, but using a dose adjusted as a result of any changes you made during the re-calibration sequence. If you choose re-calibrate, you can repeat the re-calibration. If the pump did not allow re-calibration because the adjustment required was greater than 25%, choose Exit. The pump displays the main menu, from which you can perform a fresh complete calibration of the pump.
Exit: If you choose Exit, the pump redisplays the main menu.

16.5 Remote control

A Watson-Marlow remote control footswitch or handswitch may be used to start the dose or batch. The dose will proceed once the switch is pressed. In an emergency press the STOP key to halt the dose.
The switch should be connected as shown. Or a TTL-compatible logic signal may be applied to pin 8. (Low 0V, High 5V maximum. Ground to pin 9).

Never apply mains voltage to the 25-way D socket. Up to 5V TTL may be applied across pins 8 and 9, but do not apply voltage across any other pins. It may result in permanent damage not covered by warranty.

17 Troubleshooting

If the pump display remains blank when the pump is switched on, make the following checks:

Check the position of the voltage selector switch. The voltage selector is mounted at the rear of the pump.
Check the mains power switch at the rear of the pump.
Check that mains power is available to the pump.
Check the fuse in the fuseholder at the rear of the pump.
Check the fuse in the wall plug if one is present.

If the pump runs but there is little or no flow, make the following checks:

Check that the tube and rotor are in the pumphead.
Check that fluid is supplied to the pump.
Check that the tube is not split or burst.
Check for any kinks or blockages in the lines.
Check that any valves in the lines are open.
Check that the correct wall-thickness tube is being used.
Check direction of rotation.

Tube life
Application factors that influence tube life in peristaltic pumps are pump speed and number of rollers (roller impacts/minute), chemical compatibility and viscosity of the duty fluid and suction and discharge pressure. Several tubing materials are available with different levels of life expectancy. In addition, tubing's dimensional tolerances from the manufacturing process also affect its life.
In perfect conditions of no suction or discharge pressure, pumping water in a clean environment at normal room temperature, the following nominal tube life may be experienced:

313/314
501RL

Marprene, Bioprene,
StaPure and ChemSure
less than 6,000 hours
less than 10,000 hours

Silicone
less than 250 hours
less than 250 hours

Others
less than 100 hours
less than 100 hours

Note: This is a guide only. It is not possible to make an accurate assessment of tube life except by trial of a real application.

21 313D and 314D pumpheads

The 313D pumphead has three rollers and is designed to provide higher flow rates. The 314D pumphead has four rollers to provide greater pumping precision with less pulsation in the flow. Both designs are available for 1.6mm and 2.4mm wall tubes.

New tubing can be loaded easily into the flip-top design. The top closes with a "clamp and stretch" action to locate the tube in the correct position and with the correct tension.

Standard and extension pumpheads are bayonet mounted. This ensures easy cleaning and fast set up.

21.1 313D and 314D installation and removal

Always isolate the pump from the mains power supply before opening the guard or performing any positioning, removal or maintenance activity.

Installation

Engage the pumphead drive slot with the end of the pump drive shaft. Continue to align the pumphead until the bayonet engages with the mounting plate. Turn the pumphead clockwise until it locks into an upright position.

Removal

Push the locking lever back and turn the pumphead anti-clockwise until it is free from the mounting plate.

21.2 313D and 314D tube loading

Switch off the mains supply. Lift the flip-top track until it is fully open.
Set the tube clamps to the correct tube size. The track must be fully open. Align the scale on both sides of the pumphead. If the tube is slippery, or if there is a high suction lift, the tube clamps may need a smaller setting to secure the tube.

Select enough tube length for the curve of the pump track. Slide the tube into the open pumphead. The tube must not be twisted or stretched against the rollers.
Ensure the tubing locates in the centre of the tube clamps. Carefully lower the track. Check that the tube is not crushed in the clamps or over-stretched.

When using Marprene tubing

Re-tension new tube after the first 30 minutes of running. Stop the pump and release the flip top. Allow the tube to settle naturally across the rollers. Re-clamp the tube. Re-start the pump. This will correct the normal stretching that occurs with new Marprene tube. The correct tension is essential for good tube life.

25 501RL pumphead

The 501RL and 501RL2 pumpheads are suitable for tubing with internal diameters up to 8.0mm. The 501RL is set during manufacture for use with 1.6mm wall tubing and 501RL2 is set for 2.4mm wall tubing.

The spring-loaded rollers give extended tube life. The pumphead can be run clockwise, for best tube life, or anti-clockwise for higher pressures. The tool-lockable guard should be locked shut while the pump is in use.

25.1 501RL and 501RL2 installation

Always isolate the pump from the mains power supply before opening the guard or performing any positioning, removal or maintenance activity.

The rotor and track may be removed from the pump for cleaning or to reposition the track on the pump in one of three positions.

The rotor grips the drive shaft via a split collet. To remove the rotor, hold it firmly and remove the central rotor retaining screw.

Pull the rotor from the drive shaft, leaving the collet on the drive shaft. If the collet adheres to the rotor, it can be removed by partially re-inserting the rotor retaining screw and tapping it gently. Ensure that the dog within the collet properly re-engages the drive shaft when you reassemble the unit.

The 501RL or 501RL2 track is secured with a locating screw. The track will fit on the drive in three orientations. To change its orientation, remove the track locating screw. Align the track and re-fit the track locating screw. Refit the rotor. Tighten the rotor screw to a torque of 3Nm.

25.2 501RL and 501RL2 tube loading

Switch off the mains supply. Unlock and open the pumphead guard.
Select a minimum length of 240mm of tubing. Fit one end of the tubing into a clamp.
The rotor has tube guide rollers that pull the tube into the pumphead during loading. Turn the rotor carefully until the tube guides pick up the tube. Continue to turn the rotor, and feed the tubing in between the guides.

When the tube has gone round the pump track fit the other end of the tubing into the clamp.
Check that the tubing has fitted naturally against the track for best tube life. Release the clamps and adjust the tubing if it is slack, twisted, or stretched.
The tube clamps can accommodate various tube diameters by pushing in, or pulling out, the grip bars within the clamp. Set the clamps to apply the minimum necessary pressure to the tubing to hold it in position.
Restart the pump. Free the downstream clamp for a short time, while the pump is running, so that the tube can find its natural length. Keep fingers clear of the moving rotor. Shut and lock the guard after adjusting the tube.

When using Marprene tubing

Re-tension new tube after the first 30 minutes of running. Stop the pump and release the tube clamp at the outlet of the pump. Pull any slack tube from the pumphead and re-clamp the tube. Re-start the pump. This will correct the normal stretching that occurs with new Marprene tube. The correct tension is essential for good tube life.

25.3 501RL and 501RL2 rotor settings

The 501R and 501R2 pumpheads are factory-set to give optimum tube life with Watson-Marlow tubing. We recommend that the rotors are not adjusted and that other types of tubing are not used.

If the rotor needs re-aligning we recommend the rotor is returned to Watson-Marlow for correct adjustment. Or contact our after-sales department for further information.

Check moving parts of the rotor from time to time for freedom of movement. Lubricate pivot points and rollers occasionally with Teflon lubricating oil.
