Karcher Pressure Washer Cylindrical Head Pump Set9.002-552.0

What does the head pump do for the pressure washer?

When the pressure washer is powered on, the head pump uses an internal mechanism to create a high-pressure stream of water. It effectively removes dirt, grime, and other debris from surfaces. 

The head pump pressurizes the water flow and allows it to be delivered with force through the spray nozzle or lance. This pressure enables efficient cleaning of a wide range of surfaces, including driveways, vehicles, patio furniture, and more.

What causes pressure washer head pump failure?

If you're pushing your pressure washer to the limits with prolonged and heavy-duty use, it can put a strain on the pump and eventually lead to failure. Skipping regular maintenance tasks like cleaning, lubricating, and inspecting the pump can also cause issues. 

Be cautious about using a water supply that's contaminated with debris or chemicals as they can clog the pump or damage its internal parts. 

Over time, wear and tear is inevitable, especially with all that high-pressure action. 

Is it a genuine spare part?

This head pump set by Karcher is a genuine pressure washer replacement part. Your pressure washer can work good-as-new in cleaning surfaces.
