What’s the Difference Between a Triplex Plunger Pump vs Axial Pump?  

If you’re wondering what the main differences are between a triplex plunger pump vs axial pump, you’ve come to the right place. In this article, we’ll be discussing the differences and I’ll review some of the best models on the market.

And you can see my best triplex replacement pump recommendation: the AR North America triplex pump on Amazon.

Triplex pumps have their name because of their three plungers, or pistons, that pump water through the washer. Triplex pumps are powered by gas engines and they are responsible for putting the PSI (Pounds per Square Inch) pressure into the water.

Triplex pumps are created with higher quality components and materials than axial cam pumps. When it comes to triplex plunger pump vs axial pump, the former will last for a much longer period of time. A longer running life is definitely one of the advantages of a triplex pump.   

I highly recommend this AR North America Triplex pump on Amazon as my #1 triplex replacement pump choice.

I really appreciate the heavy-duty construction: it's made of a special alloy aluminum with a bronze base to give you maximum strength and working hours. I love the high-quality stainless steel plunger rods on this AR triplex pump available on Amazon.

This horizontally mounted AR triplex pump works well with all gas pressure washer models up to 4,000 PSI and 3 GPM. And it doesn’t take long to get set up because it has a 3/8” quick connect. And you can check Amazon’s price on the AR Triplex pump.

Professional contractors are always on the lookout for reliable equipment to avoid any equipment downtime. Downtime mean lost income. So it’s no surprise that most professional contractors prefer triplex plunger pump vs axial pumps.

Triplex plunger pumps also have an edge over axial pumps because of the higher PSI (Pounds per Square Inch) they produce.  Higher PSI means more cleaning power. But, you’ll pay more for a triplex pump, than you will for an axial cam pump.

Axial pumps are connected to the pressure washer engine, making them direct drive pumps. This means three things:

1.      They run at the same speed as the pressure washer engine,

2.      They have less number of parts compared to a triplex pump, and

3.      They aren’t as durable as that of triplex pumps.

    2. Price

    An advantage of axial pumps is that they are more affordable than triple plunger pumps, while still giving you enough pressure to handle homeowner cleaning jobs.

    When it comes to triplex plunger pump vs axial pump comparison, price matters a lot, and this is the reason axial pumps are so popular with regular homeowners. My advice: if you need to use your pressure washer for less than 40 hours in a year, the axial pump is a good option to consider.

    And you can see my top recommended horizontal replacement pump: the Generac Universal Pump available on Amazon.

    Which Triplex or Axial Replacement Pump Should I Buy?   

    If you are planning to run your pressure washer for more than 40 hours a year, I recommend that you go for the triplex pump.

    Here is an essential tip you should remember when you’re planning to replace your pressure washer:

    Check that the new replacement pump matches the specs of your existing pressure washer pump. Make sure that the PSI or Pounds per Square Inch and the GPM or Gallons per Minute ratings match. The mount type matters too, whether it its horizontal or vertical. You don’t need to pick the same replacement pump brand but remember that you need to match the specifications when you’re replacing your pressure washer pump.

    Triplex Plunger Pump vs Axial Cam Pumps  –  Good Maintenance Will Make Them Both Last Longer

    Whether you choose the triplex or axial pressure washer pump, remember that proper maintenance is very important! It’s the best way to make your unit last longer.

    Protect your investment by doing the following:

    ·        Check the oil level of your pump before you power up the engine. Do this every time and make it a part of your routine.

    ·        Change the oil every spring.

    ·        Make sure to read the manual that comes with your unit for more maintenance instructions.

    I hope you learned about a lot about the differences of a triplex plunger pump vs axial pump.
