Sherwood Pump 15000K-SHW Neoprene Impeller Kit with Gaskets 12-Blade

The Sherwood 15000K-SHW is an OEM neoprene rubber impeller kit designed for Sherwood marine raw water pumps. This complete service kit includes the impeller, gasket, O-ring, and a technical service guide — everything needed for a proper impeller replacement in a single package.

The flexible 12-blade neoprene impeller delivers excellent elasticity and snap-back performance, ensuring reliable self-priming and efficient fluid transfer in marine engine cooling, bilge, and industrial processing applications. Neoprene is the industry-standard material for flexible impellers and is well-suited for fresh and salt water transfer duties where small amounts of oil or diesel may be present.
