Watson-Marlow 521VI/REMC, 521F/REMC, 521P/REMC, 521FX/REMC: 0-2 bar IP55 pumps fitted with LoadSure low-pressure element pumpheads
521 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.
520REM medium-pressure LoadSure element pumphead features large swept volume with sprung rollers for high accuracy
Chemically-resistant polyphenylene sulphide track and rotor, and stainless steel rollers and bearings
Low rotational speeds greatly increase tube life and system reliability
Clutched rotor for rapid, effortless tube loading
Rugged, tool-unlockable guard
521VI 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.
Varmeca integral inverter offering 10:1 control ratio: 63 rpm, 220 rpm and 275 rpm maximum speeds
Stop/forward/reverse control and analogue or digital remote control. There is a PROFIBUS option. 521F Fixed speed drives are three-phase powered
Flow rates from 2.5 ml/min to 4,600 ml/min
Other speeds are available on request 521FX Duplex fixed speed drives have twin pumpheads allowing two channel pumping
There is a choice of speeds: 55 rpm and 183 rpm
Flow rates to 860 ml/min from each channel
Twin 520R2C pumpheads for balanced flow in two channels
521P Pneumatic, variable speed drives offer 5:1 control ratio. They require a filtered and lubricated 7 bar air supply. An exhaust silencer is fitted and static build-up is prevented by earth bonding.
High torque, reversible four-vane pneumatic motor
Variable speed: 5:1, max 257 rpm
Flow rates from 11 ml/min to 4,100 ml/min
ATEX II 2G (Zone 1) available on request
