KNF Metering Pump(Germany)


KNF offers a range of diaphragm-metering pumps to dose liquids in the milliliter and microliter range. These pumps are characterized by outstanding precision and consistent performance, long service lives and low maintenance requirements. The various materials available for the components in contact with the media permit the dosing of neutral, aggressive and corrosive liquids.

KNF FEM dosing pumps are based on a very simple design. The stepper motor causes a cam to rotate and this, in turn, moves the diaphragm up and down. This vertical movement causes pressure changes in the pump chamber which, combined with the operation of the inlet and outlet valves, produce the pump action.
