Read below to learn about the three types of pressure washer pumps on the market - and which ones can be easily replaced if you're having trouble. My tips will save you time, work and money!

Three Types of Pressure Washer Pumps to Choose From

Currently, there are three types of pumps that are found on pressure washers:

1. Wobble

2. Axial Cam

3. Triplex



Wobble pumps are the most common type on the market. You'll generally see them on most of the economical electric pressure washers sold to homeowners -- including Karcher units.

These wobble pumps are less expensive to build. Unfortunately, these are not designed to be replaced and if you're having wobble pump issues, you'll have to replace your entire cleaning unit. You cannot switch these out if they fail. These are built to last for about 300 working hours.  

Axial cam pumps can be found on more heavy-duty electric and gas units that are sold to homeowers and contractors. These pumps have larger bearings & oil reserves and can run harder and longer. They are more reliable than wobble units, offer higher PSI and you can expect them to run 600-700 working hours before needing repairs or replacement. Yes, you can replace a worn-out axial cam unit with a new one.

And then there are triplex pumps that you'll see on very high quality, contractor-level units. Triplex pumps have the longest life expectancy, but they have the highest price tag.

Which Pump Should You Choose?

My advice is to choose the pressure washer pump that's best suited for the type of cleaning you're going to do:


Do you plan on just cleaning around your house & garage? About once a month? Or less? Then I would recommend a unit with a wobble pump because it's economical and designed for your type of occasional cleaning.

Or do you plan to pull out your pressure washer several times a month? Do you really like taking on heavy-duty cleaning or paint stripping jobs? Want to buy a unit for the long haul? Then you should consider investing in a unit with an axial cam pump.

Or are you thinking about starting your own pressure washing business? Then you'll really want to invest in a contractor grade unit with a triplex pump. You don't want to lose time & money by dealing with repairs.
