  • Smooth pulseless flow provides precise, leak-free delivery of fluids
  • Suction shoe design provides higher delivery pressures and temperatures, plus increased efficiency.
Magnetically driven, precision-geared pump heads provide smooth, accurate, pulseless fluid delivery. The magnetic drive and static seals keep fluids securely inside and potential contaminants out. Chemical resistant materials handle a wide range of materials (due to wetted parts). Pump heads are compact and easy to service. Modular design offers flexibility—configure to your specific needs.

Service kits include: gears, suction shoe, shaft seals, and springs.

  • Q:

    Can the micropumps be used to pump more viscous fluids (~12,000cp). There will be minimum inlet pressure, so I'm concerned with cavitation/bubble formation. Thanks!

      The maximum viscosity for this pump head is 100 cp. It is not capable of pumping more viscous fluids than that.

  • Q:

    When does the internal bypass on this pump head begin to open? Is there a way to adjust the setting of the internal bypass?
    Asked on 11/19/2012 by Mike

    1 answer



      The bypass is set at 45 psi at the factory. The bypass will start to open around 20 psi and then are fully open when they reach 45 psi, based on the factory setting. The bypass is adjustable and based on an 80 psi spring, but this will never reach full bypass if set that high (80 psi) as it would decouple first.
