Solenoid dosing pumps

The FMM range of solenoid powered diaphragm pumps allows easy dosing within the microliter range. By manually adjusting the stroke length, it is possible to alter the single dispense volume and calibrate the dosing pump to fit the system. Lifetime performance for the FMM 80, and FMM 20 are in excess of 500 million and 2 billion strokes, respectively.
