Key Components of a Pressure Washer



Understanding the main parts of a pressure washer is crucial before delving into diagrams. Below is an overview of the most common components.

1. Pump



The core component that pressurizes water. Pumps typically come in axial or triplex configurations and are often the most critical part needing repair.

2. Motor or Engine



Provides power to the pump. Electric pressure washers use electric motors, while gas-powered models have internal combustion engines.

3. Unloader Valve



Regulates the pressure output by diverting excess water back to the inlet or to a waste outlet, preventing damage and maintaining consistent pressure.

4. Spray Gun



The handheld component that controls the flow of high-pressure water. It often includes a trigger for activation.

5. High-Pressure Hose



Connects the spray gun to the pump, capable of withstanding high pressure.

6. Nozzle



Attached to the spray gun, nozzles determine the spray pattern and pressure. Common types include 0°, 15°, 25°, 40°, and soap nozzles.

7. Chemical Injector



Allows for the application of cleaning solutions during operation.

8. Water Intake Filter



Prevents debris from entering the pump, protecting internal components.

9. Detergent Tank



Stores cleaning detergents or chemicals for use during washing.

10. Pressure Switch



Automatically turns the pump on or off based on pressure settings.
