What is a pressure washer pump?

A pressure washer pump is an essential component of a pressure washer system. It is responsible for pressurizing water for cleaning purposes. The pump takes in water from a water source, such as a garden hose or a water tank, and increases its pressure to create a powerful stream of water. This concentrated stream of water is then used to remove dirt, grime, and other contaminants from surfaces.

There are two main types of pressure washer pumps: axial pumps and triplex pumps. Axial pumps are commonly found in less expensive and lightweight pressure washers, while triplex pumps are typically used in heavy-duty and professional-grade pressure washers. Triplex pumps are known for their durability and ability to handle high pressures.

The pressure washer pump is often powered by an engine or an electric motor. The engine or motor drives a crankshaft, which is connected to the pump’s pistons. As the crankshaft rotates, it pushes the pistons back and forth, creating the pressure that forces the water out of the pump.

The pump itself is made up of several key components, including the inlet and outlet valves, pistons, and seals. The inlet valve allows water to enter the pump, while the outlet valve controls the flow of water out of the pump. The pistons are responsible for creating the pressure, and the seals ensure that there are no leaks or loss of pressure.

Over time, the pump may experience wear and tear, resulting in a loss of pressure or other issues. It is important to regularly maintain and repair the pressure washer pump to keep it functioning properly. With proper care and maintenance, a pressure washer pump can last for many years and provide reliable cleaning power.
