6 Do's and do not's
Do not build a pump into a tight location without adequate airflow around the pump.
Do not strap the control and mains power cables together.
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) 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 minimize 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.
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.
7 Installation
Pump
Site the pump on a flat, horizontal, vibration-proof surface allowing a free flow of air around it. Ensure there is 0.5m of straight tubing before the pumphead inlet and after the pumphead outlets. Close coupled simplex pumps will require bolting down with four M8 bolts through the gearbox foot mounting holes.
AC motor
- Ensure that mains voltage/frequency are in accordance with motor nameplate information.
- Secure protective conductor connections.
- If a three-phase motor is running in the wrong direction, interchange any two phases.
- Close unused cable entrance holes and the terminal box itself in a dust and watertight manner.
- A current overload relay should be fitted to a contact breaker. Connect the motor in accordance with the wiring diagram which will be found in the motor terminal box.
- When a thermal protection switch is fitted in the motor, the leads will be found in the motor terminal box. They should be connected to stop the pump if the switch operates. The switch will open circuit at an over temperature condition. See below for the connection of the drive motor showing possible ancillary switches and protections.
- Emergency stop
- Start
- Stop
The ancillary switches are rated to 220/240V 1ph 50Hz. The Start contact should have a sprung return which will disengage following energisation of the coils C1 and C1/1.
 | Do not under any circumstances wire switches directly across any of the phases of a three-phase supply. If in doubt disconnect the pump immediately!
|
| Do not connect ancillary switches to the terminal box of a flameproof motor unless the switch has a suitable Exd rating for the zone area in which it is to be mounted.
|
8 Start-up
Before starting and after prolonged storage of the gear units, remove the plug from the vent screw on top of the casing to avoid excessive pressure in the gearbox, which may cause leakage at the shaft seals.
9 Troubleshooting
Should the pump fail to operate, make the following checks to determine whether or not servicing is required.
- Check the electrical supply is available at the pump.
- Check that the pump is not stalled by incorrect fitting of tubing.
| Always check to ensure that an Exd motor gearbox is suitably rated for the hazardous zone area in which it is to be mounted. Exd motors should only be installed by Exd qualified personnel.
|
| Any deviation from normal operating conditions (increased power consumption, temperature, vibrations, noise) or warning signals by monitoring equipment suggest malfunction. Inform the responsible maintenance personnel at once to prevent the trouble from worsening. If in doubt disconnect the pump immediately.
|
10 AC motor maintenance
- Remove any dust deposits from the fan cover to avoid overheating.
- Ensure that the bearing cage is packed to about 1/3 with evenly distributed lubricating grease.
- Select the correct lubricating grease from the table in the back of this operating instruction.
11 Gearbox maintenance - Simplex (single pumphead) units
- Change lubricant every 10,000 working hours or after 2 years.
- Combine a lubricant change with a thorough cleaning of the gear unit.
- Extreme working conditions (high air humidity, aggressive media and large temperature variations) will reduce the interval between lubricant changing intervals.
- Select the correct lubricating oil from the table in the back of this operating instruction.
12 Gearbox maintenance - Duplex (twin pumphead) units
The gearbox is filled for life with synthetic lubricant so no maintenance is required.
13 Varmeca drives
Varmeca drives: overview
The Varmeca drive is an IP65 integrated electronically-variable speed drive fitted to a standard enclosure IP55 motor gearbox. Standard Varmeca drives are single-phase but three-phase Varmecas are available.
Standard Varmeca drives are set up for manual control with the run command enabled. Current will be applied directly to the motor as soon as mains power is switched on. Subsequently, speed, direction of rotation and stop control can be achieved from the control knob and keypad.
For information on how to set up the Varmeca for remote control, please refer to the Leroy Somer Varmeca-20 manual.
| This Varmeca-20 must be connected to an approved earth terminal. It is imperative that the equipment is powered via an isolating device and a circuit-breaking device (power contactor) which can be controlled by an external safety system (emergency stop, fault detector).
|
The Varmeca-20 is fitted with safety devices which stop the motor in the event of a fault. The motor can become jammed for mechanical reasons. Voltage fluctuations and power cuts may also stop the motor.
Removing the cause of a shutdown can lead to restarting, which may be dangerous for certain installations. It is essential that the user guards against the motor restarting after shutdown, if this is undesirable.
13.1 Varmeca drives: installation
- The standard Varmeca integrated drive requires no connection other than to the mains power supply.
- The Varmeca motor fan cools the whole unit. Make sure that the ventilation air inlet is free of obstruction.
- It is the responsibility of the owner or user to ensure that the installation, operation and maintenance of the inverter complies with health and safety regulations of the relevant country of use.
| Before carrying out any work, disconnect and lock the drive power supply. For single phase units, wait two minutes to make sure that the capacitors have fully discharged. After connection work, make sure that the seals are firmly in place, and the screws and cable glands are watertight to ensure IP65 protection. Clear any condensation from the drain holes at the bottom of the motor.
|
13.2 Varmeca drives: connections
- The voltages on the power terminal blocks and the cables connected to them may cause fatal electric shocks. The drive stop function does not protect against these high voltages.
- The drive power supply must be protected against overloads and short circuits.
- It is vital to respect the rating of protection devices.
- Connections should be made with copper conductors only.
13.3 Varmeca drives: cables and protection devices
- Circuit breakers must be of the D-curve type suitable for a motor with an inverter.
- Comply with the size of protection (gl) fuses given in the table below.
- The cable size may vary according to legislation applicable in the country of use, which will take precedence over the values given in the table below without exception.
| Power | VMA rating | Current
(A) | gl fuses or circuit breaker (A) | Cable
(sq mm) |
230V/1/50/60Hz | 0.37kW 1/2HP | A
21M-037 | 4 | 10 | 1.5 |
110V/1/50/60Hz | 0.37kW 1/2HP | A
22M-037 | 9 | 16 | 2.5 |
NB: The mains current value is a typical value which depends upon the source impedance. The higher the impedance, the lower the current. The fuses (UL approved) are intended for installations capable of delivering 5,000A maximum at 480V.
13.4 Varmeca drives: commissioning / start-up
- Remove the cover and connect a suitably rated mains
cable via the cable gland to connection points L1, L2 and PE (earth)
of the Varmeca terminal block.
- Secure the connection cover and cable gland into position,
ensuring that the IP65 sealing is not compromised.
| The Varmeca must not be switched on with the connection cover removed.
|
| The
motor Run command has been enabled: the motor will
start as soon as it is switched on. |
- Power-up at the mains: the green indicator lamp lights and remains on continuously.
- Start rotation by pressing a direction button for one second.
- Set the speed reference using the side control knob, adjusting speed between 8Hz and 80Hz. The speed control knob is calibrated in percentages of maximum speed.
- Press the Stop button to stop the unit.

13.9 Varmeca care and maintenance
- Temperature variations and excessive humidity encourage the formation of condensation. If this occurs, the condensation drain plugs at the bottom of the motor should be removed, even in a very humid atmosphere.
- No specific servicing is required for Varmeca-20 motors, apart from regularly removing dust from the fan grille and the cooling fins at the bottom of the unit.
- Dismantling the Varmeca-20 while it is under warranty will invalidate the warranty.
14 Air motors
| The air motor is designed for air only. Do not allow corrosive, flammable or explosive gases or particulate material to enter the motor. Water vapour, oil-based contaminants, or other liquids must be filtered out. The recommended air pressure should not exceed 100 PSIG maximum.
|
| Always disconnect the air supply before servicing.
|
Installation
A muffler is supplied with the air motor, but not installed. Install a moisture trap and filter in the air line ahead of the motor. If condensates need to be flushed out of the motor, use clean, dry air at low pressure. For efficiency of output and speed control, use air lines of the same size or next pipe size larger than the intake port of the motor. A four-way valve which can be connected by piping to both air ports of the motor will make reversing possible. Use a pressure regulator or a simple shut-off valve to obtain desired power and conserve air to regulate speed and torque.
Lubrication
Use a detergent SAE #10 automotive engine oil. Lubrication is necessary for all moving parts and rust prevention. We recommend that an automatic air lubricator be installed in the air line just ahead of the motor. The lubricator should be adjusted to feed one drop of oil for every 50-75 CFM of air going through the motor.
- Manual lubrication Add 10-20 drops of oil every eight hours of operation through the inlet port while the pump is shut down.
- Automatic lubrication An In-line oiler should be adjusted to feed one drop per minute for high speed or continuous duty use. Do not overfeed oil as contamination of the exhaust air may occur.

16 620RE, 620RE4 and 620R Key safety information
| Before opening the pumphead guard please ensure that the following safety directions are followed.
|
- For close-coupled drives, ensure that the pump is isolated from mains voltage.
- Ensure that there is no pressure in the pipeline.
- If a tube failure has occurred, ensure that any product in the pumphead has been allowed to drain through the controlled waste to a suitable drain.
- Ensure that protective clothing and eye protection are worn if hazardous products are being pumped.
17 620RE, 620RE4 and 620R Safe-guarding
- Primary safety on 620 series pumps is provided by the tool-lockable pumphead guard. On electrically-powered cased 600 series pumps, secondary (backup) protection is provided in the form of an electrical interlock which stops the pump if the pumphead guard is opened (and only for so long as the guard is opened). The electrical interlock on cased pumps should never be used as primary protection. Always disconnect the mains power supply to the pump before opening the pumphead guard.
- Only primary protection through the tool-lockable guard is provided on pneumatically powered 621 close-coupled pumps. Only primary protection through the tool lockable pumphead guard is provided on 621 series pumps fitted with industrial AC motors, but an interface kit to allow mains power to be switched by the pumphead guard interlock is available as an extra-cost option.
18 620RE, 620RE4 and 620R Pumping conditions
Pressure and viscosity
- All pressure values in this operating instruction, from which performance and life figures have been calculated relate to peak pipeline pressures.
- Although rated to 4 bar working pressure, this pump will generate in excess of 4 bar working pressure if pipeline restrictions are in place. In instances where it is critical that a working pressure of 4 bar is not exceeded, pressure relief valves should be installed in the pipeline.
- For pumping duties of 2-4 bar pressure, use standard STA-PURE tube elements or 73 Shore hardness Marprene/Bioprene. "TM" in the tube element’s product order code denotes suitability for this pressure.
- To maintain performance at pressures above 2 bar, avoid running the pumphead below 50 rpm. If low-flow, high-pressure operation is necessary, switching to a smaller tube is recommended.
- When pumping duties of 0-2 bar pressure, use 64 Shore hardness elements or the standard range of continuous peristaltic pump tubing.
- Viscosity handling is maximised by using 73 Shore hardness Marprene/Bioprene or STA-PURE tube elements in the pumphead.
- Ensure that there is always a minimum of one metre of smooth bore flexible tubing connected to the discharge port of the pumphead. This will help minimise any impulse losses and pulsation in the pipeline. This is especially important with viscous fluids and rigid pipework.
19 620RE, 620RE4 and 620R Pump installation
A correctly engineered installation will promote the best possible tube life, so please ensure that the following guidelines are followed:
- Avoid tight pipeline bends, pipe reducers and excessive lengths of smaller bore tubing than that in the pumphead, particularly in pipelines on the suction side.
- Ensure that connecting pipe work and fittings are suitably rated to handle the predicted pipeline pressure.
- If rigid pipework comes in close proximity to the pumphead, a drop-out section of pipework will simplify tube replacement. When using element pumpheads, ensure that a minimum of 1m of flexible interface pipework is connected between the pumphead and any rigid pipework.
- Ensure that the controlled waste blanking plug is in position if the controlled waste port is not in use. See below.
- It is advisable to use controlled waste pipe work if pumping hazardous, aggressive or abrasive fluids or products which will harden in contact with air.
- When connecting waste pipe work to the controlled waste port using the coupling adaptor supplied, ensure that there is adequate clearance underneath the pumphead. Waste pipe work should run to a suitable container or drain.
- The leak detector installation procedure is included in the leak detector kit.
- If unsure of an installation please contact your local Watson-Marlow Technical Support Office for further assistance.
20 620RE, 620RE4 and 620R General operation
Opening the pumphead guard
- Unlock the guard with a 5mm Allen key or a screw driver.
- Open the guard to its full extent. This creates the maximum clearance between the tube ports and guard to remove the tubing.
Engaging/disengaging the rollers
- The extent of travel of the roller release levers is indicated below. Do not try and force the levers beyond their normal extent of travel as this will damage the rotor.
- To engage the rollers snap the roller release levers counter clockwise making sure that the rollers locked out against the tubing. To disengage the rollers, snap the release levers clockwise to their disengaged position. For high pressure tubing elements or four roller pumpheads, the 5mm Allen key can be used to aid leverage when engaging/disengaging the rollers with the release levers.
| Make sure that fingers are clear of the front face of the rotor hub when using the roller release levers.
|
Pre-load checks
- Before loading tubing, ensure that all rollers rotate freely, that the tube ports and location grooves are clean and that if in use, the controlled waste pipe work is free of any obstructions.
Closing the pumphead guard and start-up
- Ensure that the guard seal is clean, replacing it if necessary.
- Ensure that the rollers are engaged and locked out against the tubing
- Close the guard and push it against the track until the latch engages.
- Connect suitable pipe work to the pumphead using the appropriate connectors for the tube element.
Continuous tubing clamp location in 620R pumpheads
- Select the appropriate tube clamp set for the tubing size to be used.
- Locate the two "U"-shaped track clamp halves into the pumphead ports (The "U"- shape ensures correct loading)
- Locate the corresponding guard clamp halves which have raised "T" locating sections, into the slots on the inner guard face above and below the guard hinge. Push and slide into their locked position.
- Closing the guard will align the two halves of the clamp around the tubing.
21 620RE and 620RE4 tube element loading
- 620RE element pumpheads are factory set to accept Watson-Marlow LoadSure tube elements. Pumping performance will be adversely affected if LoadSure elements are not used.
- Disengage rollers
- Locate one of the "D"-shaped flanges into the lower port. (The "D" flange ensures that the element can only be loaded correctly).
- Wrap the tube element around the disengaged rollers of the rotor.
- Locate the second "D"-shaped flange into the upper port.
- Ensure the flat face of each "D" flange sits flush to the flange sealing face of the track.
- Engage rollers
- Close the guard and push it against the track until the latch engages.
Tube element loading
22 620RE, 620RE4 and 620R Continuous tube loading
- 620R continuous tubing pumpheads are factory set to accept Watson-Marlow 600 series 3.2mm wall tubing. Pumping performance will be adversely affected if Watson-Marlow tubing is not used.
- Select the tube clamp set which is correct for the tubing size to be used.
- Disengage rollers
- Locate one end of the tubing into the lower port "U" clamp and hold in position.
- Wrap the tubing tightly around the retracted rollers, making sure that there is no twisting through its length.
- Locate the other end of the tubing into the upper port "U" clamp.
- Hold both ends of the tubing in one hand maintaining tension around the rollers.
- Engage rollers
- Close the guard and push it against the track until the latch engages
- Ensure that continuous tubing is not loosely clamped at the pumphead ports.
- Ensure that when the pump is re-started all of the rollers have re-engaged. A roller which has not re-engaged will "click" continuously. No damage will occur if this happens but the roller should be re-engaged manually using the 5mm Allen key. Please refer to the Troubleshooting section.
Continuous tube loading
23 620RE, 620RE4 and 620R Tube element or continuous tube removal
- Unlock the guard and disengage the rollers.
- Disconnect the tubing from the external pipeline.
- Remove the tubing from the pumphead.
24 620RE, 620RE4 and 620R Maintenance
Scheduled maintenance
- The stainless steel pumping rollers run on sealed bearings and do not require lubrication.
- Remove the rotor and lubricate the follower rollers and roller engaging mechanisms with a lithium-based grease. This should be carried out every six months for intermittent duties and every three months for 24 hour duties.
- If fluid is spilled inside the pumphead, flush the pumphead out with water and mild detergent as soon as possible. If specific cleaning agents are required to clean the spillage, please consult Watson-Marlow Technical Support Office before proceeding, in order to confirm chemical compatibility.
- If the rotor needs to be removed, refer to the guidelines below.
Roller adjustment
620 pumpheads have provision for adjustment to reset the roller/track gap to compensate for wear after extended service in arduous applications.
Roller/track gaps can only be accurately judged without tubing in the pumphead. The gap should be 4.6mm for 3.2mm wall tubing and 5.5mm for LoadSure elements.
If the gap is more than 0.2mm greater than these dimensions, the following may be carried out:
- Note the number on the roller arm to which the engraved line on the hexagon-headed main roller pin corresponds.
- Remove the circlip (snap-ring) and roller pin.
- Relocate the main roller pin, resetting the engraved line to one number lower. For example, if the engraved line was at "-1", reset it to "-2" to reduce the roller track gap.
- Ensure the roller pin is correctly seated into the roller arm thrust washer. Replace the circlip.
Rotor removal and re-location
- Remove the rotor cover and central locating bolt using a 5mm Allen key. Pull the rotor off the keyed shaft, remove the key and clean thoroughly. Do not use tools to lever the rear face of the rotor away from the inner face of the track, it should come off by hand.
- To replace the rotor, locate the key into the keyway and apply a thin layer of grease over the shaft and key. Align the keyway of the rotor to the shaft key and slide the rotor into position, ensuring that a positive "stop" is achieved and ensure that the full length of the drive shaft is fitted into the rotor.
- Do not force the rotor into position. The rotor will slide into place easily if correctly aligned.
- Tighten the hexagonal locating bolt to a nominal torque of 10Nm using a 5mm Allen key.
- The rotor bolt, which is impregnated with "Loctite 218" thread lock, should be subjected to a maximum of three removals/relocations before renewal. To avoid rotor bolt renewal after three removals, apply "Loctite 222" thread lock to the rotor thread before relocation. This is critical to ensure prolonged, secure location of the rotor hub to the drive shaft. Failure to complete this action will invalidate the terms and conditions of the pumphead warranty.
- Replace the rotor cover.
When closing the guard, check it does not make contact with the rotor. If it does, then the rotor has been fitted incorrectly. Re-open the guard, remove and refit the rotor, and close the guard.
Track removal (close coupled AC motor gearboxes)
- Remove the rotor.
- Disconnect the controlled waste pipework if attached.
- Loosen the four track retaining screws using a Number 2 Pozi-Driv screwdriver.
- Disconnect the mains interlock if connected to a mains contactor
- Withdraw the track fully from the gearbox.
Track re-location (close coupled AC motor gearboxes)
- Ensure that the track is clean.
- Fit the track over the gearbox boss.
- Align the track horizontally so that the location holes are aligned with the threaded gearbox holes.
- Tighten the four track retaining screws using a Number 2 Pozi-Driv screwdriver.
- Re-connect the guard interlock controlled waste pipework if required.
25 620RE, 620RE4 and 620R CIP and SIP
General
- Unlock the guard and disengage the rollers within the tube zone.
- Close the guard and squeeze against the track until the latch clicks.
- Observe a 1m safety area.
CIP
- LoadSure tube elements and continuous tubing can be cleaned using CIP processes.
- Ensure that the tubuing material is chemically compatible with the cleaning agent that is to be used.
- If cleaning agents are spilled over the pumphead, wash down immediately.
- Ensure that controlled waste pipework is fitted to allow a safe release of cleaning agent in the event of a tube failure.
SIP
- Only STA-PURE tube elements can be used in a steam in place sterilisation processes.
- STA-PURE tubing elements can be sterilised to 3A Class two and FDA minimum recommended standard which is 121C (250F) at 1bar (14.5 psi) saturated steam for 20 minutes.
- Monitor the process continuously .
- If a tube failure occurs, shut down the process. Do not touch the pumphead until a 20 minute cooling period has been observed.
- Ensure a 20 minute acclimatisation period is observed before running the pump following SIP.
- Ensure that controlled waste pipework is fitted to allow a safe release of steam in the event of a tube failure..
- Ensure a 1m safety zone is maintained around the pumphead during SIP cycles.
| Ensure that the pumphead door is closed and locked before SIP cleaning commences.
