Triplex Plunger Pump Reviews

If you are on the lookout for reliable triplex plunger pump reviews, this page will help you. I’ll quickly show you how a triplex pump works and give you my recommendation for the best replacement models on the market.  

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

A triplex plunger pump is a reciprocating positive-displacement pump, with three plungers, that is powered by a gas engine. It’s designed to mechanically put pressure into the water as it moves inside your power washer. And out of your spray wand.

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.

Compared to an axial cam pump, triplex pumps are manufactured using heavier bearings and stronger/longer lasting materials. Due to their higher PSI ratings and dependability, triplex pumps are the preference of pressure washer professionals. And the working life of a triplex pump is a lot longer than an axial cam pump.

    2. Price

    And since we are discussing triplex plunger pump reviews, let’s also talk about the other two kinds of pumps used in power washers: axial cam and wobble.

    Featured on electric washers that cost about $200, or less, wobble pumps are designed for shorter working lives than axial cam or triplex pumps. They’re economical, but they just don’t last as long as other pump types. Because wobble pumps are designed as a permanent part of electric washers, wobble pumps cannot be repaired or replaced. If they get damaged, your whole power washer will have to be replaced.

    Axial cam pumps, on the other hand, are used on higher quality gas and electric power washers. They’re direct drive pumps and axial cam pumps are connected directly to the engine or motor of the pressure washer. As opposed to wobble pumps, they have a longer working life and are more dependable. The best part? They can be replaced or repaired if they get worn out.

    Triplex Plunger Pump Reviews: Buying Tips

    As you go through my triplex plunger pump reviews, I wanted to remind you that there is no need for you to get the same pump brand when looking for a replacement pump. If your power washer, for example, features a CAT triplex pump that’s worn out, you can use another brand of triplex pump to replace it.

    In fact, you can select any brand name of triplex pump as long as the new replacement pump and your old pump have the same GPM (gallons per minute) and PSI (pounds per square inch) specifications.

    Lastly, the mounting direction of the triplex pump (whether vertical or horizontal) should also be a match.

    Thanks for reading my triplex plunger pump reviews.
