Watson-Marlow 620SN/RE4, 620UN/RE4, 620DuN/RE4: 0-2bar NEMA 4X (IP66) low-pulsation pumps fitted with LoadSure tubing element pumpheads
  

Tough, rugged 620N cased pump drives offer NEMA 4X (IP66) ingress protection which prevents the entry of dust particles and protects against powerful jets of water. They are designed for industrial and washdown environments. All models include MemoDose for accurate, easy, single-shot dosing. Remote, analogue or digital control of 620UN and 620DuN models is achieved via labelled standard terminal blocks within the 620N module on the rear of the pump.

Pumphead

620RE4 LoadSure tube element pumphead

620RE4 is a high-performance, accurate, four-roller pumphead with LoadSure rapid tube element change technology. 4mm wall elements in 12mm or 17mm bore sizes allow pressures up to 4bar (60psi) and flow rates up to 13 litre/min (3.32gpm) with minimized pulsation.

Elements are available with industry-standard tri-clamp sanitary fittings; and with Cam and Groove fittings for industry.

 

620RE LoadSure tube element pumphead

620RE is a high-performance, accurate, two-roller pumphead with LoadSure rapid tube element change technology.

 

620L twin-channel pumphead

620L is a specialist 2bar, six-roller pumphead designed for accurate dispensing to ±0.5%. Minimal pulsation is achieved by splitting the inlet flow into two tubes passing over twin, offset tracks. The two sets of out-of-phase pulses cancel each other out when the channels merge.

 

620R continuous tubing pumphead

620R pumphead accommodates 3.2mm wall continuous tubing in four bore sizes from 6.4mm to 15.9mm, giving up to 16 litre/min (4.2gpm) flow at up to 2bar (30psi) pressure.

Tubing is available in eight materials for almost any chemical requirement.

Drives

These cased pump drives offer NEMA 4X (IP66) ingress protection, which prevents the entry of dust particles and protects against powerful jets of water. They are designed for industrial and washdown environments. All models include MemoDose for accurate, single shot dosing. Remote control of 620UN and 620DuN models is achieved via labelled standard terminal blocks within the 620N module on the rear of the pump.

620SN is a manual pump offering ultimate economy of ownership, with calibration and manual control via a large key membrane keypad

620UN is a remote control pump with analogue speed inputs and status outputs

620DuN is a process pump with RS485 and full industrial connectivity.

620Bp is the ultimate process pump with PROFIBUS connectivity
