Danfoss Pump Filter & O Ring D Drum Bfp11/21 071N0063

Accessories for BFP. 071N0063 65325684

The Danfoss Pump Filter & O-Ring Kit (071N0063) is a genuine service replacement set for Danfoss BFP11 and BFP21 oil pumps. This filter kit ensures clean, stable fuel delivery to the burner by capturing sludge, rust, and particulate contamination before it reaches the nozzle or pump internals.

This updated kit now uses Danfoss/Ecoflam new part number 65325684, replacing the older reference 2020704. It includes the high-efficiency D-type filter element and the correct O-ring for sealing the pump cover.

Replacing this filter during routine servicing prevents nozzle blockage, ignition issues, pump wear, and inconsistent burner performance.
