Description
The FMM 20 pump is a solenoid driven diaphragm pump which has been designed to dispense an accurate volume of 20 ul per stroke. The volume can be adjusted between approx. 5 and 25 ul thus allowing the pump to be calibrated to fit the parameters of the application. It is also possible to run the pump at 20 Hz in order to prime system.
An electrical impulse 12/24V sent to the solenoid creates a magnetic field which in turn draws the diaphragm down compressing a spring. As the impulse stops the spring pushes the diaphragm up which coupled with the patented valve system creates a pumping action.
Membrane pump features
- Long lifetime: over 2 billion strokes
- Frequence: 0-20 Hz (flowrate 0 – 30 ml/min)
- Flow tight in both directions At rest the pump is sealed internally for pressures up to 0.5 bar.
- Quiet running
- Suction height (mWg): 4
- Max. allowed pressure (bar): 1.0
