Watson-Marlow 620SN/RE4, 620UN/RE4, 620DuN/RE4: 0-2 bar 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.
RE pumpheads: flow rates up to 18 l/min at 2 bar (30psi) peak pressure
RE pumpheads using STA-PURE PCS elements: flow rates up to 18 l/min at 4 bar (60psi) peak pressure
RE4 pumpheads: flow rates up to 13 l/min at 2 bar (30psi) peak pressure
Precise 2,650:1 speed control range from 0.1 to 265 rpm in 0.1 rpm increments
Retractable rollers for tube loading and CIP and SIP
Rugged, tool-unlockable guard
Dual voltage, 115V/230V 50/60HZ
620SN:
Manual control via 9-key display pad
Simple calibration to display flow rate
MemoDose for accurate, single-shot dosing
620UN
As 620SN, plus:
Analogue speed control (0-10V or 4-20mA inputs)
Remote control via industrial logic with digital status outputs
0-10V or 0-1478Hz analogue speed feedback
620DuN
As 620UN, plus:
PIN-secure process protection: two levels of process set-up security
Digital network control using RS485
Numeric keypad for direct entry of flow and pump settings
Twin analogue inputs for simultaneous flow adjustment with two signals (supersedes diaphragm pumps' stroke adjustment)
Wide choice of metric or US flow units
Easy calibration for precise metering
