Pentair Gasket (Impeller to Shaft Sleeve) | CSPH/CCSPH Series Commercial Pump | 33455-8044

The Pentair 33455-8044 is the OEM replacement impeller-to-shaft-sleeve gasket for the CSPH and CCSPH Series commercial pump line — specifically for non-20 HP configurations. What It Does This gasket seals the interface between the impeller and the shaft sleeve inside the pump's wet end assembly. A compromised gasket at this joint allows water to bypass the impeller seal, reducing hydraulic efficiency and accelerating internal wear. Replacing this gasket during pump service restores the integrity of that connection and protects the shaft sleeve from corrosion caused by water intrusion.

This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering. Pro Tip The compatibility data for this part explicitly excludes 20 HP configurations — confirm your pump's horsepower rating on the motor nameplate before ordering. When servicing the wet end of a CSPH or CCSPH pump, this is also an appropriate time to inspect the shaft seal and any associated O-rings for wear; replacing worn components in the same service interval reduces the need to re-open the pump shortly after reassembly.
