XP Series Micropumps

XP Series micropumps offer our highest performance, efficiency and widest operating temperature range of -25 to 55°C to suit the most demanding applications. In common with all Disc Pumps, XP Series pumps combine silent operation, pulsation-free flow, millisecond response and high precision in a compact form factor.

  • Peak flow 2.0 L/min
  • Peak pressure 400 mbar
  • Peak vacuum -300 mbar

Performance figures shown in table are for intermittent operation at 1.4 W. See datasheets for full details.

LEE Ventus is actively developing higher performance pump designs. Contact us to discuss whether we have an alternative design that meets your requirements.


Mounting Guidance
Mount in any orientation using compliant materials. If using mounting eyes on pump body, LEE Ventus recommends using four compliant o-rings (e.g. 1.42 ID x 1.78 CS Nitrile 70 Shore A) with two o-rings per mounting eye (one above and one below the eye), Nylon M2 bolt and threaded mounting stud (e.g. Wurth Elektronik 9774050243R). This mounting scheme isolates high-frequency vibration and prevents audible noise.
