Pentair Shaft Sleeve | Sta-Rite CSPH/CCSPH Series Commercial Pump | 37447-0001L

OEM Shaft Sleeve for Sta-Rite CSPH/CCSPH Series Commercial Pumps The Pentair 37447-0001L is the OEM replacement shaft sleeve for the Sta-Rite CSPH and CCSPH Series commercial pumps. If you're sourcing this part by the Sta-Rite name, this is the correct current Pentair part number for that application. The shaft sleeve fits over the pump shaft between the mechanical seal and the impeller, protecting the shaft from wear, corrosion, and seal abrasion. When the sleeve shows scoring, pitting, or grooving at the seal contact surface, it should be replaced together with the mechanical seal to restore a proper sealing interface and prevent premature seal failure. Specifications Pentair Part Number 37447-0001L Also Known As Sta-Rite 37447-0001L (Pentair legacy brand) Fits Sta-Rite CSPH / CCSPH Series Commercial Pump Quantity Included 1 Pro Tip When replacing the shaft sleeve on a CSPH or CCSPH pump, inspect the mechanical seal at the same time. A worn sleeve almost always means the seal face has been running against a damaged surface — replacing the sleeve without the seal, or vice versa, typically results in a repeat service call. Match the part number stamped or etched on your existing sleeve to 37447-0001L before ordering to confirm fitment on your specific pump configuration.
