Jabsco 4568-0003 - Impeller
The Jabsco 4568-0003 impeller is a crucial component designed to handle various challenging pumping tasks. Constructed from durable Nitrile rubber, this impeller features 12 flexible blades and measures 2-1/4 inches (57mm) in width and 1-1/4 inches (32mm) in thickness. It comes equipped with a 5/8 inch (16mm) brass key drive shaft hub, making it suitable for use in demanding environments, such as bilge pumping or transferring heavily contaminated water, including those mixed with oil or diesel.
To ensure optimal performance and longevity, it is recommended to replace the impeller at least once a year or more frequently based on engine usage. While a properly installed impeller can last several years, following a preventative maintenance schedule is always preferable. Nitrile impellers are effective with a wide range of fluids, including oils, oil-water emulsions, diesel fuel, and more. However, if dealing with corrosive substances, flushing the pump with water after each use can extend its life.
The temperature range for Nitrile impellers spans from 50°F (10°C) to 180°F (82.2°C). It's important to note that lower temperatures may impact priming and performance, and Nitrile impellers typically deliver about 10 percent less flow than the listed pump performance. Always keep spare impellers on hand for emergencies, as they are vital for maintaining the engine cooling system's efficiency. Jabsco impellers undergo rigorous quality control to ensure reliable and long-lasting performance.
