Types of Pressure Washer Pumps
There are different types of pumps used in pressure washers, each with its own unique cleaning requirements.
Following are the different types of pressure washer pumps and discuss the best practices for cleaning each one. By understanding the different types of pumps and how to maintain them, you can ensure your pressure washer operates at peak performance and lasts for years to come.
Axial cam pumps
Axial cam pumps are a type of pressure washer pump commonly used in residential and commercial pressure washing machines. They operate by using an axial cam mechanism to create pressure, which is then used to power the water spray.
Axial cam pumps are popular due to their compact size, relatively low cost, and ease of maintenance. They are generally rated for pressure in the range of 1500-4000 PSI and flow rates up to 4 GPM.
To clean an axial cam pump, follow the manufacturer’s instructions carefully. This may involve flushing the pump with clean water after each use, checking and replacing worn or damaged parts, and performing regular maintenance to keep the pump in good working condition.
Overall, axial cam pumps are a reliable and efficient option for pressure washing tasks, and with proper care and maintenance, they can provide years of reliable service.
Triplex plunger pumps
Triplex plunger pumps are a type of pressure washer pump that uses three plungers to create pressure. They are commonly used in commercial and industrial settings due to their high pressure output and durability.
However, they require regular maintenance to prevent damage and ensure optimal performance. This includes checking and replacing seals, inspecting valves, and cleaning the pump regularly to remove dirt and debris.
If properly cared for, triplex plunger pumps can provide long-lasting and effective performance for a variety of pressure washing applications.
Wobble plate pumps
Wobble plate pumps are a type of pressure washer pump that use a wobbling motion to generate pressure. They are typically found in lower-end pressure washers and can be prone to wearing out faster than other types of pumps.
Regularly clean and maintain wobble plate pumps to ensure their longevity and effectiveness. This includes checking and replacing worn out or damaged parts, such as the piston seals and bearings.
Diaphragm pumps
Diaphragm pumps are a type of pressure washer pump that use a flexible diaphragm to displace water. They are popular for their ability to handle a wide range of pressures and flow rates, making them ideal for a variety of cleaning tasks.
To clean a diaphragm pump, start by turning off the pressure washer and disconnecting the hoses. Next, remove the diaphragm and inspect it for damage or wear. If it’s damaged, replace it with a new one.
Clean the inside of the pump housing with a soft brush and mild detergent, then rinse thoroughly with water. Finally, reassemble the pump and hoses and test the pressure washer to ensure proper operation.

Maintenance Tips for Pressure Washer Pumps
Maintaining your pressure washer pump is essential to keep it functioning optimally and prolong its lifespan. A well-maintained pump ensures your pressure washer delivers the required water pressure and flow rate for efficient cleaning.
Following are some maintenance tips for pressure washer pumps, which will help you clean and maintain your pump easily and effectively.
Regularly checking for leaks and wear
Regularly checking for leaks and wear is an important aspect of maintaining pressure washer pumps. Leaks can cause the pump to lose pressure and reduce its effectiveness. Wear and tear can also lead to a decrease in performance and may eventually require replacement of the pump. To prevent these issues, it is recommended to inspect the pump regularly and replace any damaged or worn parts as needed. Using a pump protector can help extend the lifespan of the pump by lubricating its seals and preventing rust and corrosion.
Using appropriate pump oil and changing it as needed
One important maintenance tip for pressure washer pumps is to use the appropriate pump oil and change it as needed. Pump oil lubricates and protects the pump’s internal parts from wear and tear, which can reduce the pump’s efficiency and lifespan.
Use the manufacturer-recommended pump oil, as using the wrong type of oil can damage the pump. The pump oil should also be changed regularly, as old or contaminated oil can lead to reduced pump performance and even damage.
To change the pump oil, first, make sure the engine is turned off and the pressure washer is cool. Then, remove the oil fill cap and drain the old oil into a container. After that, replace the oil with the recommended type of pump oil up to the recommended level. Replace the oil fill cap and run the pressure washer for a few minutes to circulate the new oil throughout the pump.
By using the appropriate pump oil and changing it as needed, you can keep your pressure washer pump running smoothly and efficiently for longer.
Winterizing the pressure washer pump
Winterizing your pressure washer pump is an important maintenance step to ensure its longevity and prevent damage during the cold months.
This involves draining any remaining water from the pump, adding antifreeze, and storing it in a dry, protected area. Remove any hoses and attachments and store them separately. Proper winterization can save you from costly repairs and replacements in the future.
Storing the pressure washer properly when not in use
Proper storage of a pressure washer when not in use is essential for maintaining its pump. Firstly, make sure the machine is turned off and unplugged. Next, empty any remaining water from the pump and hoses, and store it in a dry, cool place away from direct sunlight.
It is also advisable to use a pump saver solution to protect the pump’s internal parts from corrosion and damage during storage. Finally, avoid storing the pressure washer in freezing temperatures, as this can cause damage to the pump and other components.
Conclusion
Cleaning your pressure washer pump is crucial for its longevity. Begin by turning off the machine and unplugging it. Detach the hoses and run clean water through the pump. A brush can help remove any dirt or grime. Reattach the hoses and test the machine before using.
As we wrap up our discussion on how to clean a pressure washer pump, emphasize the significance of regular pump maintenance and cleaning.
