Review of the Best Replacement Pump for Pressure Washers

If you have one of the very popular electric pressure washers on the market, it's probably outfitted with a wobble pump. Electric pressure washers with wobble pumps are inexpensive to buy.  But I wanted to warn you that wobble pumps are not  replaceable.  If your wobble pump breaks down, on your electric pressure washer, you'll have to buy an entirely new washer.  You can expect a wobble pump to last up to 300 working hours.

But if you have a gas pressure washer, you probably have an axial cam pump which is more powerful and reliable than wobble pumps. They are more reliable & powerful than any wobble pump and they are available on gas  pressure washer units.  Yes, washers with axial cam pumps are priced a little bit higher, but they're built better & will produce higher PSI. (The higher the PSI or Pounds per Square Inch, the faster and deeper the cleaning.)  Axial cam pumps are built with larger bearings and oil reservoirs so they can run harder & longer. On average, axial cam pumps last around 600-700 hours before needing repairs or servicing.

Lastly, there are triplex pumps.  They're 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 higher price tag. 

Here's my handy pressure washer pump chart with my 2 top recommended replacement axial cam pumps:

    My Best Axial Cam Pump Replacement Tip:

    Before You Buy the Best Replacement Pump for Pressure Washers:  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!

    Now you have the important information you need to find and maintain the best replacement pump for pressure washers.
