Water pump impellers are common in shower drain sump pumps, some bilge pumps, wakeboard ballast pump systems, oil changing systems and lots of other applications. The pump impeller itself is simply a series of rubber vanes molded around a hub. The vanes are flexible, and the hub rotates on an eccentric within the pump housing, which has a stainless steel liner. The tips of the impeller vanes can wear out from simple use, but if the motor is often run in silty or sandy conditions, this abrasive material can accelerate impeller wear.  The impeller is a vital component of your engine's cooling system. If an impeller fails, the pump can’t pump cool water to the engine causing your engine to overheat. Keeping a spare impeller on board is a good idea in case of sudden failure.



A pump O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus. It is a loop of elastomer with a round cross-section, designed to be placed within the groove of a threaded connection. O-rings are a popular way to create a seal. The connection of the two threads is met and compressed together, creating a seal at the interface. The O-ring works as a water pump mechanical seal protecting the connection against leaks.
