About this item

Designed with maintenance-free high-accuracy motor and a graphical interface—makes setup and operation easier than ever!

Digital interface with graphical LCD shows pump performance and operating modes—continuous run, timed dispense, copy dispense, or volume dispense
Select your preferred language from the user-friendly menu for programming and operation
Dispense by Volume in ml (0.001 to 9,999 mL), L, or gal; Copy—1 to 9,999 dispense cycles; or Time—time interval of on/off cycles (1 sec to 99 hr, 59 min, 59 sec per cycle)Antidrip function ensures dispensing accuracy
Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio
Models with open-head sensor stop drive motor when pump head is opened

These precision drives offer analog remote control options and simple programming—ideal for automated process applications. Drives feature a programmable dispense interval that lets you set the delay between dispense cycles for convenient, automated dispensing. Programmed calibration ensures dispense and display accuracy—drive stores one calibration value per tubing size.

Program the drive via the simple membrane keypad; keypad lock/unlock feature protects settings. Motor is reversible so you can purge tubing before or after pumping and pump fluid in either direction.
