KNF Flodos AG is proud to present two new dosing pumps driven by two-phase stepper motors. The possibility to use existing motor con-trollers is very attractive for OEM manufacturers.
The new pump series is available in two versions the FEM1.02 and FEM1.09 with different flow ranges, 0.2 – 20ml/min and 0.9 – 90ml/min respectively. Both pumps can be used against pressures of up to 6.0 bar with a minimum loss of flow against varying conditions.
A high level of dosing accuracy, repeatability and long term repro-ducibility makes these metering pumps ideal for applications where long life and no maintenance are of utmost importance. A new valve system ensures that air can not collect in the pump head and helps to reduce the head volume to a minimum.
A large selection of materials can be used for the wetted parts mak-ing this pump type suitable for pumping aggressive liquids. Dia-phragm pumps don’t have moving seals making them very leak tight which is a big advantage when handling liquids which can crystallize out. All pumps can be equipped with an integrated pressure relief valve guaranteeing a pressure safe system.
KNF also offers a control module for the pump allowing lots of differ-ent possibilites making the integration into your system very simple.
