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

 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.
