Micro Piston Pump

Micro Piston Pump

MP series piston pump is a family of maintenance–free OEM pump designed for precise fluid dispensing, especially for analysis instrument. Excellent precision and accuracy ensure the analysis result, 10 million cycles reduce the maintenance cost of the analysis instrument. There are a variety of pump configurations, different material for different chemical resistance, different structure for different fluid properties, different resolution for different precision and speed.

Flow rates:-≤200ml/min

Max. Number of Channels:1


Applications:

For low volume application, especially for analysis instrument.
