ConceptFeatures / Advantages

The FMM 20 pump is a solenoid driven diaphragm pump which has been designed to dispense an accurate volume of 20 µl per stroke. The volume can be adjusted between approx. 5 and 25 µl thus allowing the pump to be calibra- ted to fit the parameters of the application. Long lifetime Over 250 million strokes. Adjustable dispense volume 5-25 µl It is also pos-sible to run the pump at 20 Hz in order to prime system. This allows the pump to be calibrated. Large flow range The pump can be operated between 0-20 Hz (flow rate of 0 - 30 ml/min). Flow tight in both directions An electrical impulse 12/24V sent to the solenoid creates a magnetic field which in turn draws the diaphragm down com- pressing a spring. As the impulse stops the spring pushes the diaphragm up which coupled with the patented valve system creates a pumping action. At rest the pump is sealed internally for pressures up to 0.5 bar. High chemical resistance Large choice of wetted materials. Self priming Capable of pumping both liquids and gases. The pump can be mounted in any position using either a manifold or tubing. Different connection possibilities can be seen on the last page. Quiet running Noise suppression system. High repeatability Stable pump characteristics over the entire life time.
