Self-cleaning filter for installing between flanges

Model of a metal full flow filter with flanges

Bild

Plastic filter insert made of PTFE or high performance thermoplastic material. Optionally, we offer plastic housing for clamping with metal reinforcing (all medium touched parts are made of plastic)

Centrifugal pumps like sleeved-motor pumps, magnetic coupling pumps, or pumps with axial face seal, need a cleaned partial product flow to avoid damaging from abrasive substances to the axial face seal as soon as to the split-tube or the split-case. On this occation, the application of a full flow filter with integrated cross flow filtration is an ideal solution. The full flow feed flows axially through the cylindrical filter cell. Using the side connection of the filter housing, the cleaned-up fluid will be drained off. As a rule, the filter is mounted on the pumps outlet side. We offer a selection between a filter version with flanges and a filter version clamped among flanges.
