More About this Item

These 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. Precise PWM speed control (±0.1%) maximizes accuracy and efficiency while the brushless motor gives you quiet, maintenance-free reliability. 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.
