Jabsco 8-Blade Nitrile Impeller 14750-0003-P for Marine Water Pumps and Bilge Pumps

The Jabsco 8-Blade Impeller, part number 14750-0003-P, is a nitrile replacement impeller built to fit a variety of pumps used in marine applications, including marine engine water pumps and bilge pumps. Its nitrile construction offers compatibility with oil products and handles a wide range of fluids, including oils, oil and water emulsions, diesel fuel, lower fraction hydrocarbons, kerosene, and lubricating and machine cutting oil, making it well suited to pumps that see contaminated water or oily fluid rather than clean coolant alone.

The impeller uses a single flat drive with 8 blades and a brass insert/hub for the drive connection. It is supplied as a kit, including a gasket, O-rings, and a glycerin lubricating packet to aid installation. Flexible impellers are a wear item, and it is common practice to inspect and replace them annually as preventative maintenance against pump failure, so keeping a spare 14750-0003-P on board is a practical step for anyone relying on this pump for engine cooling or bilge duty.
