Pumps & Pump Parts

For tough jobs, heat matters. Hot water pressure washers use high temperatures and pressure to break down grease, oil, and grime faster than cold water alone. The result is a deeper clean, less effort, and better results across a wide range of applications.

Find the Right Pressure Washer Pump for Your Machine

Not all pumps are created equal. Selecting the correct replacement pressure washer pump depends on your machine’s specifications and how you use it.

When choosing a pump, consider:

PSI (Pressure Output): Match your pump to your machine’s required pressure rating
GPM (Flow Rate): Ensures proper water volume and cleaning performance
Drive Type: Direct drive vs. belt drive systems
Compatibility: Make sure the pump fits your unit and engine setup

Whether you’re running a compact unit or a heavy-duty commercial system, we offer pressure washer pumps for sale that meet a wide range of performance needs.

Types of Pressure Washer Pumps

Understanding pump types helps you choose the best option for your application.

Direct Drive Pumps

Connected directly to the engine
Compact and cost-effective
Ideal for lighter-duty or portable units

Belt Drive Pumps

Driven by a belt and pulley system
Run cooler and last longer
Best for heavy-duty and continuous use

Triplex Pumps

High-performance, rebuildable pumps
Designed for commercial and industrial pressure washers
Longer lifespan and consistent pressure output

When Should You Replace Your Pressure Washer Pump?

A failing pump can reduce cleaning power and put strain on your entire system. If you’re experiencing any of the following, it may be time for a pressure washer pump replacement:

Loss of pressure or inconsistent output
Pulsing or surging water flow
Leaks coming from the pump housing
Unusual noise during operation
Visible wear or corrosion

Replacing your pump at the right time can prevent costly downtime and keep your equipment performing at its best.

Seal kits and valve kits
Unloaders and regulators

Replacement plungers and components

Routine maintenance and timely repairs can significantly extend the life of your pump and reduce long-term costs.

Pump and Pump Parts FAQs

What does a pressure washer pump do?

The pump is the core of your pressure washer, responsible for drawing in water and increasing its pressure before sending it through the system. It’s what turns a standard water supply into a powerful cleaning stream.

What types of pressure washer pumps are available?

The most common types include axial (wobble plate), triplex plunger, and piston pumps. Axial pumps are typically used in residential units, while triplex pumps are built for commercial and heavy-duty applications due to their higher durability and pressure capabilities.

What pump parts may need to be replaced over time?

Common replacement parts include seals, valves, plungers, manifolds, and repair kits. These components wear down with use and are critical to maintaining proper pressure and performance.

How do I know if my pressure washer pump is failing?

Signs of a failing pump include reduced pressure, leaking water, unusual noises, or inconsistent operation. If your system isn’t performing like it used to and other components check out, the pump or its internal parts may need repair or replacement.

How do I choose the right replacement pump or pump parts?

You’ll need to match key specs like PSI, GPM, shaft size, and mounting style to your existing unit. Using the correct part ensures proper fit, safe operation, and optimal performance. Having your model and serial number on hand will make selection much easier.
