LPV Series Pumps

Standard Performance Model

Configuration A

Configuration B

Unless otherwise specified, dimensions are in inches [mm]. Drawings are not to scale.

  • Wetted materials: piston and port head (see table below), UHMW-PE
  • Dispense accuracy: ± 0.5% (100% total volume)
  • External valving required
  • Motor: stacked can bipolar stepper motor
  • Drive current:
    • 260-290 mA (RMS) per phase (250 µL and 750 µL volumes)
    • 210-240 mA (RMS) per phase (50 µL volume)
  • Cycle life: these pumps will typically operate across a minimum of 5 million cycles on water, depending on application conditions. Click here for additional details.
