This is the complete pre-filter basket lid assembly for the Davey StarFlo DSF pool pump series. The kit contains all three components needed to restore a secure, leak-free seal on the pump’s pre-filter housing: the lid cover, the locking ring, and the O-ring. Replacing the full set at once ensures proper fitment and prevents recurring leaks or air ingestion caused by worn individual parts.<\/p>\n
Designed to fit the Davey StarFlo single-phase pumps DSF150, DSF200, DSF250, DSF300, and DSF420 \u2014 including the CE-marked variants (e.g. DSF300CE, DSF420CE) sold exclusively in Europe \u2014 as well as the 3-phase models DSF3003F and DSF4203F. Always cross-reference your pump’s model label with the Davey spares diagram before ordering.<\/p>\n
As a genuine Davey spare part (Davey part number 33154SP), this lid set is manufactured to the exact tolerances of the original components. Aftermarket alternatives often result in poor sealing, premature O-ring failure, or a locking ring that does not engage correctly \u2014 any of which can allow air into the system, reducing pump performance and potentially causing cavitation damage.<\/p>\n
The lid set should be replaced when you notice water leaking from the pre-filter housing, difficulty seating or tightening the locking ring, visible cracks in the cover, or a perished and flattened O-ring. Replacing all three components together rather than just the O-ring is best practice during any lid-off service visit, ensuring the assembly returns to factory condition.<\/p>","protected":false},"excerpt":{"rendered":"
