A pressure washer pump is the beating heart of any pressure washer.
It's easy to forget, as you compare different pressure washer models, that the quality of your pump is just as important as the quality of your engine!
You can see my #1 universal pump choice: the Generac Universal Pump on Amazon. With 3000 PSI, horizontal mounting and 3/4" shaft, it works with virtually all pressure washer brands & engines!

Let's review the best pressure washer pumps on the market, then talk about the three main pressure washer pump types so you can choose the best replacement pump for your washer and budget. I'll also share some important pressure washer pump repair & troubleshooting tips.
Here's my pressure washer pump reviews to help you choose the best pressure washer pump for your washer engine:
I highly recommend the AR Triplex Plunger Pump on Amazon. This AR triplex pump has a new high efficiency design, oversized bearings for a longer working life and stainless steel rods for added strength.
This AR triplex pump has 8 plungers, ceramic coated stainless steel crankcase and is designed for engines with a 1" shaft. You'll get a whopping 4,000 max PSI, 4 GPM and 3400 RPM!
Check Amazon's price on the AR Triplex Plunger Pump.
I highly recommend the AR pump RMV2.5G30EZ on Amazon because when I compare the power, quality of its components and price - it's an outstanding value for any homeowner. And I love that fact that the thermal relief valve is also included on this axial pump!
This AR pressure washer pump will give you up to3,000 PSI power, with 2.5 GPM. That's more than enough cleaning power for just about any homeowner DIY job.
It has a 3/4" shaft connection, is horizontally mounted, has the AR EZ Start feature - and also has the handy chemical injection system built-in.
I also want to mention that this AR pressure washer pump is pre-filled with special synthetic oil and is sealed. This means that you don't need to fool around with adding oil and the oil is maintenance-free for the life of the pump.

There are 3 main pressure washer pump types:
1. wobble pump
2. axial cam pump
3. triplex pump
Each of these 3 pressure washer pump types have different ranges of maximum PSI, GPM, lifetime working hours and price points. Let's talk about advantages and disadvantages of each of these important pressure washer pump types so you can choose wisely.
A wobble pump, also known as a wobble plate pump, is generally used on entry level electric pressure washers with a lower price point. Wobble pumps are cheaper to build and they are usually not replaceable.
If you have a pressure washer with a wobble pump that breaks, you'll have to replace your entire pressure washer. These pumps are generally designed to last up to about 300 working hours.
The next pressure washer pump type is the axial cam pump. Axial cam pumps are much more reliable and powerful than wobble pumps.
Axial cam pumps have larger bearings & oil reservoirs so they can run harder and longer. On average, axial cam pumps last around 600-700 hours before needing repairs or servicing.
And I should point out that axial cam pumps are the most popular pressure washer pump type outfitted on washer designed for homeowners.
The Generac Universal axial cam pump on Amazon works with virtually any pressure washer brand with 3,000 PSI, horizontal mounting and 3/4" shaft.
Check Amazon's price on the Generac axial cam pump.

The last pressure washer pump type is the heavy-duty triplex pump. These triplex pumps are most commonly seen on higher quality, contractor-level pressure washers. You'll get more PSI power and faster GPM specs out of triplex pump.
Triplex pumps have a longer life expectancy and are more efficient than axial cam pumps, but they are generally put onto pressure washers that are significantly more expensive and heavy.
You will generally get a much longer working life out of triplex pump, but you'll also see they're usually offered at a higher price point than an axial cam pump.
Check out my best triplex pump choice: the AR Triplex Pump RSV4G40-PKG on Amazon. This AR triplex pump has a new high efficiency design with oversized bearings for longer life - and stainless steel rods for more strength. It'll give you a monster max 4,000 PSI, 4 GPM and 3400 RPM.
You can check Amazon's price on the AR Triplex RSV4G40-PKG pump.
Now that you're familiar with the 3 main pressure washer pump types, you'll be able to choose the best pressure washer pump replacement.
