MP Series Piston Pump

MP series piston pump is a precision dispensing pump designed by Longer Pump, with the main function of achieving constant flow transferring of liquid. It has very high dispensing accuracy and repeatability. The service life can reach more than 5 million cycles with promised accuracy and repeatability. It is a high performance, low cost, maintenance free precision dispensing pump.

Features

  • With the unique precision transmission design, high precision components and reliable photoelectric sensor, the rated stroke dispensing accuracy is ≥99.5%. The CV of 100% dispensing is <0.1%.
  • The service life is more than 10 million cycles with deionized water. The long service life will maximize the working time of instruments and reduce maintenance cost.
  • Multiple material of piston pump head, piston and seal are available.
  • Optional flusing function to ensure the long life of transferring crystallized solutions.
  • Optional motor encoder to realize real-time monitoring of motor position.
  • Optional controller to save your system development time.
  • Customized piston pump is available according to specific requirements.
