Stack 2 pump heads with any tubing formulation for increased flow rates and for multichannel applications

Remote control capabilities via watertight connection:

Speed control input scalable 0 to 20 mA, 4 to 20 mA, or 0 to 10V

Pumping direction requires open collector or contact closure

Start/stop/purge requires open collector or contact closure

Tachometer output scalable 0 to 20 mA, 4 to 20 mA, 0 to 10V, open collector

These full-featured drives give you rugged performance and precise digital control Ideal for fluid transfer, dispensing, and metering applications in laboratory, process, and industrial environments including pharmaceutical, food & beverage, dairy, chemical, manufacturing, and water treatment. The NEMA 4X (IP66) rated housings are completely sealed, easy-to-clean, and resistant to commonly used cleaning and sanitizing solutions.


Precision drives feature a programmable dispense interval that lets you set the delay between dispense cycles for convenient, automated dispensing by time or by volume. Programmed calibration ensures dispense and display accuracy—drive stores one calibration value per tubing size. Select tubing size and enter desired flow rate—drive locks in required rpm; keypad lock/unlock feature protects settings.
