Modular Dispensing Drives


Masterflex now offers a modular peristaltic pump in their I/P line for manufacturing processes, quick fluid transfer in the lab, and industrial applications. The new Masterflex® I/P® Digital Modular Dispensing Drives from Cole-Parmer are precision digital drives with flow rates ranging from 0.0006 LPM up to 26 LPM. Three dispensing modes and low-maintenance motors add to their flexibility. Plus, the pump’s motor and controller can be placed separately for optimal convenience.

These Masterflex peristaltic pump drives feature a programmable dispense interval that lets users set the delay between dispense cycles for automated dispensing by time or by volume. To increase dispense accuracy and prevent dripping, a programmable antidrip function briefly reverses the motor at end of the dispense cycle. Precise PWM speed control (±0.1%) maximizes accuracy and efficiency while the brushless motor provides quiet reliability. Programmed calibration ensures dispense and display accuracy—the drive stores one calibration value per tubing size. Users can program the drive via the simple membrane keypad; keypad lock/unlock feature protects settings. The graphical LCD shows four operating modes and a menu-driven interface offers seven languages for programming.
