Longer MP Series Piston Pump

  • Maximum Flow rate of 200ml/min
  • Pump volume up to 5000µL
  • Ideal for micro fluid transfer
  • Very long service life with up to 10 million cycles

The MP Series Piston Pump is an OEM micro piston pump ideal for use in filing and dispensing where accuracy and precision are required. It features an impressive accuracy of over 99.5% at full dispensing.

Designed to be maintenance free

Designed to be maintenance free and offer a long service, the MP series is frequently used within the strict restrictions of the Vitro Diagnostic medical device industry. The expected life of 10 million cycles when using distilled water.

The MP series can be split into three parts: the head, the motor and the body. The head houses the piston that is powered by the motor and displaces the fluid pushing it out of the pump. Inside the body, the drivetrain is protected by seals preventing the fluid from entering and ensuring a long service life for the pump.
