Flow rate at 20 Hz
Suction height, self-priming
KNF FMM 20 is a solenoid-powered liquid pump, designed to be used in dosing in the micro-liter range. Areas of use include medical devices, ink-jet printing, water analysis, industrial dosing systems and semiconductor manufacturing.
The control module for test purposes is available on request, contact us for more information.
- Long service life, over 2 billion strokes
- Adjustable dispense volume 5-17 μl
- Large low range: the pump can be operated between 0–20 Hz, which represents a low range of 18 ml/min
- High chemical resistance
- Self priming
- Quiet running
- Flow tight in both directions
