Raritan G13 Impeller w/Teflon Washers & Pump Gaskets

The Raritan G13 Impeller with Teflon Washers and Pump Gaskets is an essential replacement component for marine sanitation and water systems aboard pleasure boats. If you've logged serious hours on the water, you know that raw-water cooling and waste-handling pumps are the unsung workhorses keeping your vessel running smoothly. When an impeller begins to wear—evidenced by reduced flow, cavitation noise, or sluggish pump performance—replacement becomes unavoidable. This Raritan G13 impeller assembly restores full pumping efficiency and is trusted by boat owners and marine technicians worldwide.

The G13 impeller is a flexible, multi-blade rotor designed to move fluids without generating excessive heat or cavitation damage. The inclusion of Teflon washers dramatically reduces friction and wear on the pump shaft and housing, extending service life and improving reliability—critical when you're far offshore and parts aren't readily available. Pump gaskets are included to ensure a watertight seal during reinstallation, preventing leaks that could compromise your system. These elastomer and composite materials are engineered to withstand the corrosive marine environment, saltwater exposure, and temperature fluctuations typical of boat operations.

This replacement kit is ideal for owners of Raritan-equipped vessels—from cruising sailboats to cabin cruisers relying on seawater cooling or macerator toilets. Installation is straightforward for any boater with basic mechanical skills; simply remove the pump housing, extract the worn impeller, and install the new G13 unit with fresh gaskets and Teflon washers. Perform this service every 3–5 years or when performance drops, depending on water conditions and usage frequency. Whether you're preparing for a long offshore passage or maintaining year-round systems, keeping a Raritan G13 Impeller with Teflon Washers and Pump Gaskets in your spares locker is smart seamanship.
