Watson-Marlow 323Du Variable-Speed Pump Drive

Enhanced control features include RS-232, auto, and remote controls

Easily maintain fluid integrity using peristaltic pumps. Only the bore of the tubing contacts the fluid, eliminating the risk of the pump contaminating the fluid or the fluid contaminating the pump. Peristaltic pumps are great for use with most liquids, including viscous, shear-sensitive, corrosive, and abrasive fluids.

Control the pump speed from 2 to 400 rpm in 1 rpm increment. Speed can be easily adjusted while the pump is stopped or running; reverse the direction with a simple push of a button. Program the pump to dispense a set amount of fluid each time using the MemoDose function. Lock the keypad to prevent changes to pump settings, avoiding any accidental changes.

The advanced features of the 323Du drive allow manual control or remote control to start/stop the pump or control the speed using analog signals (4 to 20 mA, 0 to 10 V) or an RS-232 interface. Drive accepts a 313 or 314 rapid load pump head or 314MC or 318MC multichannel pump head to achieve flow rates from 0.002 to 2000 mL/min. Pump heads sold separately.
