What to Consider Before You Buy a Pressure Washer Pump
The pump is a crucial component in any pressure washing system, and there are a few things you need to keep in mind as you go to buy one of these pumps:
- Know the type– You can choose from three types of pressure washer pumps. These are axial, triplex and wobble washers. The wobble washer will not last very long, but it is pretty cheap. It also cannot be replaced. The axial can be replaced and lasts longer. The triplex lasts the longest, is more expensive and is usually reserved for industrial pressure washers.
- Warranty- You want a pump that is going to last for a while if you pay good money for it. You can find warranties that range between 30 days and a few years, and it’s up to you to decide how long you want your pump covered for. We recommend looking for a warranty that at least covers your purchase for a full year.
- Power- Not all pumps have the same power output, and that is going to matter when you are trying to clean high up on the side of your house or get rid of some stubborn accumulation of dirt in your driveway. Pay attention to the power output to ensure you are getting something that can handle tougher jobs.
- How you will use it- One of the most important things to consider when you buy a pressure washer pump is how you plan to utilize it. If you are using it for your home, then you can get away with a cheaper one that doesn’t do as much or has a high-power output. If you are buying one for professional jobs, though, then you need a heavy-duty washer and pump that is going to perform well even after extended use.
- PSI output- How much pressure the pump can produce is measured by PSI, and you will want something pretty powerful to handle industrial work. If you are just cleaning around your home, then it won’t be a problem to use a weaker pump with a lower PSI output. For industrial work, you want something that can put out at least 3,500-4,000 PSI.

It could peel the paint right off if you are not careful. It also could lacerate your skin, so you’ll want to wear protective equipment as you use it.

Conclusion
Now that you have some options to pick from, you can choose the best pressure washer pump for your needs. As you use your new pump, just be sure you don’t place it too close to any structures or items, as the exhaust can generate intense heat and cause damage to certain surfaces.
Good pressure washer pumps can be powerful tools for cleaning up your property’s exterior quickly and effectively, but you need to operate them carefully, as their power can make them dangerous. Once you have chosen a high-quality pump though, most of your safety concerns should be minimal.
