Overview
Replacement parts for the FPS 3NC (3 in) and 4NC (4 in) Series non-clog pumps, listed by Franklin Electric order number. Choose the part from the drop-down; every part is identified by its Franklin order number, which is also the SKU.
Impellers are sized by trim diameter in millimetres. The trim is the last number in the pump model (3NC-323P1-184 is a 184 mm impeller), so match the replacement to the model on the nameplate.
Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.

Fit data from FPS Wastewater Catalog M5276 (09-25), NC model parts. Where the catalog lists one part for several builds, confirm HP and phase from the nameplate.
Before You OrderConfirm the pump model and serial from the nameplate. Opening the motor chamber of an oil-filled NC motor is a service-shop job; seal and bearing work needs a clean bench and new O-rings.
