Best Pressure Washer Pump

I wrote this best pressure washer pump page to help you identify the specific type of pump you have - and I share my pro buying tips if you want to repair or replace it!

 And you can see my top replacement pump recommendation: the Generac universal pump on Amazon. Replacing this horizontal pressure washer pump is very easy and you only have to remove four bolts!  And this Generac pump has a universal design that works with all pressure washer brands. You can check Amazon's price on the Generac universal pump.

3 Main Types of Pressure Washer Pumps

Wobble pumps can be found on the many popular & economical electric pressure washers on the market.  Wobble pumps help keep the prices low on electric units,  but I want to let you know that they are not replaceable.  If your wobble pump breaks down, on your electric pressure washer, you'll have to buy a new washer. These wobble pumps are generally designed to last about 300 working hours.  

Axial cam pumps are more reliable & powerful than wobble pumps and they are available on gas  pressure washer units.  Axial cam pumps have larger bearings and oil reservoirs, than wobble pumps, so they can run harder and longer. On average, axial cam pumps last around 600-700 hours before needing repairs or servicing. They are the best pressure washer pump choice for homeowners.

My top recommended horizontal axial pump: the Generac Universal Pump available on Amazon.

Triplex pumps are the heavy duty pumps that are preferred by professionals. You'll find these on the higher end gas pressure washers. They are built to last longer than axial pumps, providing higher PSI levels, but they have a slightly higher price tag.  And they're installed on gas pressure washer units that are heavier & have more powerful PSI and GPM.

    Best Pressure Washer Pump Buying Tip:

    Before You Buy a Replacement Pump:  make sure you match the existing specs of your old pump with your new pump.  You'll want to match up the PSI  (Pounds per Square Inch), GPM (Gallons per Minute) ratings - as well as the mount type:  horizontal versus vertical. You don't have to choose the same brand name, when you're replacing your pressure washer pump, but you do  need to match the specs.

    Here's my highly recommended replacement pumps - and why I recommend them:

    This horizontal Generac pump is a universal fit - so it will work with any pressure washer brand or engine up to 3,000 PSI with a horizontal mount.

    When you compare quality & price, you just can't beat this Generac pump.

    It's shipped to you completely sealed - and ready to be installed next to your engine. I love that it comes completely sealed & with proper fluids. No leaks. Extra easy & fast installation for you. And Generac consistently produces quality pressure washer pumps. You can read other customer reviews on Amazon.com.

    This Himore Universal vertical mount pump, available on Amazon, is my top choice if you need a vertical mount replacement pump.

    This vertical mount pump with 7/8" shaft fits any model or brand of pressure washer with a maximum of 2700 PSI and 2.4 GPM.

    And this Himore Universal Vertical Pump will come to you filled with pump oil, sealed and ready to be put onto your washer. No annoying leaks or refilling. Super easy installation so you won't waste time getting your unit up & running again. 

    And it's very economically priced. You can pick it up for less than $100! You can check this item at Amazon.com's price.

    And this AR North America Triplex pump is my #1 Choice when you need a replacement triplex  pump.

     I love the construction: one piece that's made with a special alloy aluminum and bronze base. It's oversized to give you the maximum strength & longest life.

    It works  great for gas pressure washer units up to 4,000 PSI and 3 GPM. And it features a 3/8" quick connect - so hooking it up only take a few minutes. You can check this item at Amazon.com's price.

    Maintenance

    And don't forget that proper maintenance is critical for getting the most out of your pump - and protecting your investment!

    Most gas pressure washer owners manual state that you should check your pump oil level often.  I think it's best to check your pump oil level before you start the engine - each time. And it's a good idea to completely change the oil every spring.

    Check your owners manual for more maintenance instructions for your unit!
