Jet Pumps, Pump Parts and Pump Rebuild Kits for Jet Ski Personal Watercraft PWC.

A personal watercraft (PWC) jet pump is a type of pump that is used to propel a PWC, also known as a jet ski, through the water. The jet pump consists of an impeller and a jet nozzle, which work together to create the thrust needed to move the PWC forward.

The impeller is a mechanical device that is located inside the jet pump and is responsible for drawing in and accelerating the water. It consists of a series of vanes or blades arranged in a circular pattern around a central hub. As the impeller rotates, it creates a low pressure area at the center of the impeller, which causes water to be drawn in from the surrounding area. The water is then accelerated outwards towards the discharge side of the impeller, where it is directed through the jet nozzle.

The jet nozzle is a narrow, pointed opening located at the rear of the PWC that is used to direct the water flow and create the thrust needed to move the PWC through the water. It is typically adjustable, allowing the operator to control the direction and intensity of the water flow.

In general, PWC jet pumps are designed to be compact, lightweight, and efficient, in order to maximize the performance and handling of the PWC. They are typically powered by an internal combustion engine, which drives the impeller and generates the flow needed to propel the PWC through the water.
