Masterflex® L/S® Precision Variable-Speed Modular Pump Systems

Place where convenient—ideal for limited spaces, hoods, or isolation chambers
  • Flow rate 0.06 to 3400 mL/min with L/S tubing—flow rate depends on drive rpm and tubing size
  • Three digit LED display shows motor rpm — confirm speed setting at a glance
  • Reversible motor—purge tubing before or after pumping; pump fluid in either direction
  • LED indicators confirm motor direction
  • Choose between benchtop controller or washdown wall-mount controller drives
L/S® modular drives feature reversible pumping and allow you the flexibility to separate the motor from the controller. These accurate modular drives have powerful motors, speed display, and ±0.25% speed control for precise flow regulation—ideal for metering applications.

Benchtop controller drives feature a splash-resistant ABS plastic controller housing with IP33 rating and remote control capabilities via a DB9 female connector on back of controller. Wall-mount controller housing is powder-coated aluminum and IP66/NEMA 4X rated for washdown with remote control capabilities via weather-resistant connection on controller.
