Types of Pressure Washer Pumps
Understanding the different types of pressure washer pumps can help you make an informed decision when it comes to replacing your old pump or purchasing a new one. Below are the different types of pressure washer pumps and their respective advantages and disadvantages.
Axial cam pumps
Axial cam pumps are a type of pressure washer pump that use a series of pistons to create high-pressure water flow. These pumps are known for their efficiency and durability, making them a popular choice for commercial and industrial applications.
Axial cam pumps require proper maintenance and cleaning to ensure their longevity and optimal performance. If you need to replace an axial cam pump, choose a compatible replacement and follow proper installation procedures.
Triplex plunger pumps
Triplex plunger pumps are a type of pressure washer pump that use three plungers to generate high pressure water flow. These pumps are known for their durability and reliability, making them a popular choice for commercial and industrial use.
Triplex plunger pumps are capable of producing pressure up to 5000 PSI and flow rates of up to 10 GPM, making them ideal for heavy-duty cleaning tasks. However, these pumps can be expensive and require regular maintenance to ensure optimal performance.
When replacing a triplex plunger pump, choose a pump that is compatible with your pressure washer’s specifications and to follow manufacturer guidelines for installation and maintenance.
Wobble plate pumps
Wobble plate pumps are a type of pressure washer pump that uses a circular plate with a swash plate to generate pressure. They are common in residential pressure washers because they are simple, affordable, and reliable.
However, they have a lower lifespan than other types of pumps and require regular maintenance to ensure their longevity. To replace a wobble plate pump, the first step is to identify the type of pump on your pressure washer and purchase a replacement pump that is compatible with your machine.
Then, you need to disconnect the hoses, remove the old pump, and install the new pump following the manufacturer’s instructions. Take precautions and wear protective gear when working with pressure washer pumps to prevent injury.
Choosing the Right Replacement Pump
With so many options available in the market, it can be challenging to select the best pump for your pressure washer.

Be sure to consult the manufacturer’s manual or a trusted professional to ensure you select the right replacement pump for your pressure washer.
Considering the pump’s material and build quality
When choosing a replacement pump for your pressure washer, consider the material and build quality of the pump. A pump made from high-quality materials, such as brass or stainless steel, will be more durable and long-lasting.
