Diaphragm Metering Pumps FEM 1.03 ... E 755 - KNF NEUBERGER - #1

The FEM diaphragm dosing pump has been specially developed in order to accurately dose small quantities of liquid over a long period of time whereby two of its most distinctive features are its compact size and robustness (pump and electronics). The FEM pump and electronics makes a complete dosing system which is suitable for both simple as well as complex applications. With the functions „quasi continuous flow" and „batch dispensing" the FEM diaphragm pump differentiates itself from pumps based on alternative technologies eg. piston, gear, syringe and peristaltic pumps. Other interesting features are its high reliability, a favourable purchasing price and low maintenance costs.

KNF has developed a specially programmed electronic control module so that the integrated solenoid valve and the movements of the diaphragm are exactly synchronised. This results in an exact dosing which is gentle and low in pulsation. In addition to these unique pump characteristics the control module also allows a wide range of control possibilities to be used eg. serial interfaces.

The dosing pump is self priming, maintenance free and can be run dry.
