Pumps - close-coupled

600 series close-coupled pumps

Overview

Close-coupled industrial pump with 620RE LoadSure element pumphead

621F/RE, 62VI/RE, 621I/RE, 621FX/RE: 0 bar to 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 19 L/min at 2 bar peak pressure
  • RE pumpheads using GORE STA-PURE PCS elements: flow rates up to 19 L/min at 4 bar peak pressure
  • Retractable rollers for tube loading and CIP and SIP
  • Rugged, 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 230 V and 400 V three-phase power options, plus 110 V and 230 V 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 speeds
  • Flow rates from 0.09 L/min to 19 L/min
  • Stop/forward/reverse control and analogue, digital, remote and PROFIBUS control options

 621F Fixed speed drives are three-phase powered

  • There is a choice of speeds: 77 rpm and 251 rpm
  • Flow rates from 0.1 L/min to 18 L/min
  • Other speeds are available on request

 621FX Duplex fixed speed drives have twin pumpheads allowing two channel pumping.

  • There is a choice of speeds: 69 rpm and 183 rpm
  • Flow rates to 12.2 L/min from each channel

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

  • Inverter can be mounted beside the pump or remotely
  • Three-speed ranges: 6 rpm to 60 rpm; 21rpm to 213 rpm 29 rpm 291 rpm
  • Flow rates to 18.1 L/min
