Watson-Marlow 621 Series Close-coupled Industrial Pump with 620RE LoadSure Element Pumphead

621F/RE, 62VI/RE, 621I/RE, 621FX/RE: 0-2 bar IP55 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.RE pumpheads: flow rates up to 4.9 gpm at 30 psi peak pressureRE pumpheads using GORE STA-PURE PCS elements: flow rates up to 4.9 gpm at 60 psi peak pressureRetractable rollers for tube loading and CIP and SIPRugged, tool-unlockable guard 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.Varmeca integral inverter offering 10:1 control ratio: 77 rpm, 146 rpm and 261 rpm maximum speedsFlow rates from 0.02 gpm to 4.9 gpmStop/forward/reverse control and analogue or digital remote control. There is a PROFIBUS option621F Fixed speed drives are three-phase poweredThere is a choice of speeds: 77 rpm and 251 rpmFlow rates from 0.02 gpm to 4.9 gpmOther speeds are available on request621FX Duplex fixed speed drives have twin pumpheads allowing two channel pumping.There is a choice of speeds: 69 rpm and 183 rpmFlow rates to 3.2 gpm from each channel621I Inverter-controlled, variable speed drives include a stand-alone Siemens inverter to control pump speed.Inverter can be mounted beside the pump or remotelyThree speed ranges: 6-60 rpm; 21-213 rpm; 29-291 rpmFlow rates to 4.8 gpm620RE LoadSure tube element pumphead 620RE is a high-performance, accurate, two-roller pumphead with LoadSure rapid tube element change technology. 4mm wall elements in 12mm or 17mm bore sizes allow pressures up to 60 psi (4 bar) and flow rates up to 4.8 gpm (18 litre/min).Elements are available with industry-standard tri-clamp sanitary fittings; and with Cam and Groove fittings for industry. 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 60 psi (4 bar) and flow rates up to 3.32 gpm (13 litre/min) with minimized pulsation. Elements are available with industry-standard tri-clamp sanitary fittings; and with Cam and Groove fittings for industry. 620L twin-channel pumphead 620L is a specialist 2 bar, 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. Uses 4.0mm wall Y-elements in a choice of six materials, or continuous tubingTwo single channels are also availableTubing choices: 8mm, 12mm, and 16mm bore, offering flow rates from 0.00053 to 3.3 gpm (0.002 to 12.4 litre/min)Dispenses 500ml in 3.5 seconds  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 4.2 gpm (16 litre/min) flow at up to 30 psi (2 bar) pressure. Tubing is available in eight materials for almost any chemical requirement.
