General Types: Positive displacement pumps have two general groups. The groups are reciprocating pumps that use pistons and plungers, and rotary pumps, that use screws, gears, and vanes. There are two main differences between these two types of pumps.

The first one is that the piston pump has the cylinder seal attached to the piston, and the plunger pump has the cylinder seal at the stationary point. The second one is that the piston pump is driven by a drive shaft and the plunger pump is driven by a crankshaft.

The Three Types of Pressure Washer Pumps

For better understanding, the companies divide the pressure washer pumps into three categories, and they are Wobble Pump, Axial Cam Pump, and Triplex Plunger pump.

Wobble Pump

This type of pump uses a wobble plate that is connected to the drive shaft that pushes the piston back and forth. The piston sucks in the water and pushes it out with great force.

This pump is only 70% efficient because it needs to push against the water and the spring. These pumps are sealed shut before they come out from the factory and are used in low PSI (below 2500) and low GPM (below 2.0) machines.

Axial Cam Pump

This pump can work at higher PSI and higher GPM. This is an intermediate level pump that will offer you many advantages over the wobble pump. In this pump, the pistons rotate around the swash plate which is a little different from a wobble pump.

The swash plate strokes the piston, and the pistons suck up water from one side and push it out on the other side. In this operation, it rotates about the same axis as the drive shaft directly connected.

The lifespan of this pump is around 500 – 800 hours which is slightly better to wobble pumps. This kind of pump is used in most of the machines that fall under 3500 PSI.

There are two versions of this pump which are fixed and variable. In the variable version, you can adjust the angle of the swash plate.

Triplex Plunger Pump

This kind of pump is very strong that can run thousands of hours without maintenance. They can tolerate very high water pressure and are used in most of the professional-level machines. Like a car engine, the pistons drive on positive action to suck in water and push the water out with each stroke.

This pump is around 90% efficient and because they run at less RPM than the engine they run cooler. In this pump, you can replace and repair most of its parts.

Depending on your maintenance this machine gives you service. The maintenance of this machine is economical. Most of the machines that serve over 3000 PSI water use this pump.

It is definitely your decision to select the pump that you will buy for your pressure washer. You just have to think about a few important things such as product match, PSI and GPM capability, product brand and its users’ review. You must not forget to match the product to avoid unnecessary changing. Matching with the machine you have to select the PSI and GPM. Good brands always make good products for their reputation depends on it. Learn properly about a product before buying so that you can avoid future troubles.

The performance of your machine highly depends on the quality of your pump. The price of the Triplex Plunger pump is the highest among the three, then the Axial Cam pump and finally, the wobble pump. When you buy a machine, you should look for a better pump that lasts long and doesn’t need frequent maintenance. If you need to replace your pump, you should go for the better one if your machine supports it.
