Keypad entry of flow rates from 0.00079 gpm to 3.43 gpm (0.003 - 13 liter/min)
NEMA 4X wash-down and dustproof enclosure suitable for heavy industrial environments
Chemically resistant powder coated casing (exterior grade polyester)
Brushless DC motor, 2650:1 turndown, 0.1% set speed accuracy
Digital speed adjustment with choice of 0.1rpm, 0.5rpm, 1rpm, 2rpm, 5rpm and 10rpm step changes
PIN-secure Process Protection; full pump configuration protected by dual operator/supervisor PIN codes
Wire-free guard-switching stops the pump if the pumphead is opened while running
Remote control via contact closure or 5V TTL to 24V industrial logic or RS485 network control - PROFIBUS DP now available
Digital status outputs (configurable) via four relays
Analog speed control using programmable inputs (0-10V or 4-20mA) and 0-10V output (8 bit)
Speed feedback from 0-1478Hz tachometer output
Rotor/stroke control inputs allow drop-in replacement of chemical metering pumps
Fitted as standard with the new 620RE4 Mark II, minimal pulsation pumphead, for high performance tubing elements. Watson-Marlow's patented LoadSure™ elements offer one minute maintenance and ensure correct loading for long tubing life and accuracy. This pumphead can easily be positioned in two orientations (ports right or ports down) and features four stainless steel rollers which can be retracted for CIP and SIP.
