QB Laboratory Pump

Available Drive Modules: QB, QB4, QB5

Ideal for Mobile, Remote and Instrumentation

The QB pump offers the advantage of mechanical adjustment of stroke length, plus electrical control of stroke rate by voltage variation. Infinitely adjustable flow rates allow for precise fluid control, essential for dosing and metering.

  • Modular design allows for easy adaptation to different requirements and quick replacement of components.
  • Positive displacement – maintains consistent output flow even against discharge pressures up to 100 PSI.
  • Capable of self-priming up to 15 feet, making it flexible for various setups.
  • Suitable for a wide range of applications due to its ability to manage different fluid viscosities and self-priming capability.

Note: When ordering, the pump drive and pump head will be priced separately
