Components of a Craftsman Pressure Washer Pump

A Craftsman pressure washer pump consists of several key components:

Component Description
Pump Head The pump head houses the internal parts of the pressure washer pump, including the pistons, valves, and seals. It is usually made of durable materials like brass or aluminum to withstand high pressures.
Pistons The pistons are responsible for pressurizing the water by moving back and forth within the pump head. Craftsman pumps typically have high-quality pistons that can handle the rigors of pressure washing.
Valves Pressure washer pump valves regulate the flow of water and allow it to enter and exit the pump head. These valves ensure a smooth and consistent flow of water, enhancing the efficiency of the pressure washer.
Seals Seals prevent water from leaking out of the pump and maintain pressure during operation. Craftsman pressure washer pumps use durable seals that are resistant to wear and tear, prolonging the lifespan of the pump.
Drive Shaft The drive shaft connects the pump to the engine or motor of the pressure washer. It transfers the rotational motion to the pump, allowing it to generate the necessary pressure.

Understanding the components of a Craftsman pressure washer pump is essential when it comes to troubleshooting and repairing any issues that may arise. A thorough knowledge of how the pump works helps ensure its optimal performance and longevity.
