LPD Series Pumps

High Performance Model

Configuration A

Configuration B

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

  • Wetted materials: TZP, port head (see table below), UHMW-PE, and 316 SS (3000 µL dispense volume only).
  • Dispense accuracy: ± 0.5% (100% total volume)
  • External valving required
  • Home sensor (full discharge)
  • Encoder: 2 channel, quadrature
  • Motor: NEMA 17 bipolar stepper motor
  • Drive current:
    • 400-420 mA (RMS) per phase (50 µL, 250 µL and 1000 µL volumes)
    • 650-750 mA (RMS) per phase (3000 µL volume)
  • Integrated backlash compensation (except on 3000 µL dispense volume)
