We manufacture a wide range of pump elements for a large number of applications

These include compressor lubrication systems, gas compression and precise dosing of liquids

These components are made of different materials depending on the pumped media to which they must correspond

For the pump elements to work efficiently, a precise clearance fit is indispensable
