Types of pressure washer pumps

Axial cam pump (drive shaft driven piston pump)

Axial cam pumps are typically used on mid-range pressure washers, offering a balance of performance and price. The operating mechanism includes a cam that rotates to drive a piston to supply water and pressure in a synchronized rhythm.

Axial cam pumps can handle considerable pressures and flows and are suitable for residential and light commercial use. However, these pumps typically have a service life of 500-800 hours compared to higher-end models because their direct-drive designs tend to generate more heat and wear, making it as a perfect choice for pressure washers rated up to 3500psi. According to the different pump materials, BISON axial cam pumps are divided into aluminum axial cam pumps and copper axial cam pumps. Click to learn about different models.

Triplex plunger pump (crankshaft driven piston pump)

When use a professional-grade pressure washer, you might encounter a triplex plunger pump. These pumps work through a crankshaft that drives pistons, similar to a car engine. The design ensures consistent, pulse-free flow, maximizing efficiency.

Triplex plunger pumps have the highest pressure and flow capabilities of the three types, capable of producing up to 5000 PSI. BISON triplex plunger pump can effectively prevent the pump body from being corroded through surface oxidation treatment. At the same time, pump comes equipped with innovative patented booster valve, designed to efficiently reduce pump temperature, thereby extend the lifespan of the pump body. Renowned for their robustness and enduring operational capabilities, these units boast an average service life exceeding 1000 hours, rendering them well-suited for heavy-duty commercial applications.In addition, we have also launched different types for engine pressure washers and electric pressure washers: triplex plunger pumps suitable for engine and triplex plunger pumps for electric motors.

Although triplex plunger pumps perform commendably, they are more expensive and have higher maintenance requirements than other pumps. Therefore, they may not be ideal for those looking for an affordable option or those who are new to pressure washers.

Wobble plate pump(drive shaft driven piston pump)

Because of their simplicity and affordability, wobble plate pumps are often found in entry-level pressure washers. These pumps use an oscillating mechanism to drive a piston that pressurizes the water. This design means each piston is always partially pressurized, resulting in slightly less efficiency.

For pressure washers under 2500 PSI, there is enough pressure and flow for basic tasks, but wobble plate pumps have limitations in heavy-duty applications—its pressure and flow capabilities are the lowest of the three. Additionally, when these pumps wear out, due to their integrated design with the motor, they often cannot be replaced, requiring the entire unit to be replaced.

In addition to these two broad categories, there may be other varieties on the market, but they appear less frequently and are usually specialized for certain industrial or niche applications.

By understanding the different types of pressure washer pumps, you can choose based on your usage needs, ensuring your pressure washer performs optimally and lasts longer. Consider your specific needs: pressure (PSI) requirements for cleaning tasks, flow (GPM) requirements, and durability and maintenance needs to make an informed decision. Read on as we discuss further how to choose the right pump for your application and needs.

Choose the right pressure washer pump 

Selecting right pressure washer pump for your cleaning requirements involves considering several key factors:

Pressure (PSI) requirements for cleaning tasks

Pressure output, quantified in pounds per square inch (psi), stands out as a crucial factor, when choosing a pressure washer pump. For lighter tasks, such as washing cars or cleaning garden furniture, lower pressures within range of 1300 to 2000 psi are generally sufficient. However, more demanding jobs, such as removing heavy paint or cleaning concrete, may necessitate a higher PSI range, typically falling between 2500 to 3000. Therefore, knowing the psi levels required for your task will help guide your pump selection.

Traffic (GPM) requirements

When selecting the right pressure washer pump, another pivotal factor to consider is flow rate, measured in gallons per minute (GPM). GPM denotes quantity of water a pressure washer utilizes per minute, directly influencing cleaning speed. Higher GPM means faster cleaning, but it also means more water consumption. Understanding your efficiency needs and water conservation preferences will help you decide on the right GPM for your mission.

Durability and maintenance requirements

The durability of pressure washer pump is frequently depends on its construction quality and regular maintenance. Such as superior quality triplex plunger pumps, tend to be more durable owing to their robust build. However, they also require more regular maintenance. Despite this, they necessitate more frequent upkeep. If you anticipate frequent use of your pressure washer or engage in demanding tasks, opting for a sturdier pump could be a judicious decision. Conversely, for less frequent tasks or lighter cleaning, a more affordable, lower-maintenance pump may be more suitable.

Keeping these factors in mind will help you decide on a pump that will not only meet your cleaning needs, but also provide durability and match your maintenance capabilities. Understand your cleaning requirements, evaluate your preferences, and invest wisely in a pump that meets them all.

In the next section, we'll discuss what you need to know about replacing your pressure washer pump (if necessary).

Signs your pressure washer pump needs replacement

Pressure washer pumps usually do not fail without warning. Often, they will give signs that they are nearing the end. Pressure loss, unstable operation, or unusual noise during operation are common indicators. Should your pressure washer encounter difficulty in building pressure, or if pump emits unusual sounds like rattling or grinding, it might be to contemplate replacement.

Choose a compatible alternative

Are pressure washer pumps universal? Pressure washer pumps are not universal. While some assert their universality, the truth is that they only prove effective for parts. Before purchasing, remember that the new pump must be compatible with your pressure washer. Consider the considerations we discussed earlier, such as pressure (PSI) requirements, flow (GPM), and durability. If your pressure washer initially featured a wobble plate pump and your tasks demand increased power, contemplating an upgrade to an axial cam or triplex plunger pump could be a worthwhile consideration. However, you need to make sure that the pressure washer's motor can support the new pump.
