Watson-Marlow 621F/RE4, 62VI/RE4, 621I/RE4, 621FX/RE4: 0-2bar IP55 low-pulsation pumps fitted with LoadSure tubing element pumpheads

  

621 close coupled pumps offer IP55 ingress protection for light industrial environments. They offer rugged, industrial pumping, with all the pumphead features of cased drives, but at the lowest whole-life cost.

621VI Varmeca close coupled drives bring 10:1 speed control, constant torque output and total reliability to the industrial environment. The drive offers 230V and 400V three-phase power options, plus 110V and 230V single-phase. Control is by a large speed knob and forward/reverse switching.

621F Fixed speed drives are three-phase powered

621I Inverter-controlled, variable speed drives include a stand-alone Siemens inverter to control pump speed.

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

621 series close-coupled drives offer rugged, industrial, quality pumping, with all the pumphead features of cased drives, but at the lowest possible whole-life ownership cost.
