More About this Item

These precision drives offer digital and analog remote control (I/O) options and simple programming—ideal for automated process and network 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 or remotely; keypad lock/unlock feature protects settings. Motor is reversible so you can purge tubing before or after pumping and pump fluid in either direction.
