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 Pressure Washer Pump Types

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.

pressure washer pumps

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.

  • This pump can run dry, produce high pressure and self-priming.
  • If any of the parts of this pump gets spoilt then you cannot repair it, you have to replace it. They are not as efficient as the other pumps.

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.

  • This pump has a longer life and more efficient than the wobble pump. You can adjust the water flow if you adjust the swash plate angle.
  • This pump becomes very hot while working and takes the time to cool down. This pump can cause excess vibration if it is not properly balanced.

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.

  • These pumps are very efficient that is less prone to leaks with very high-pressure tolerance. Because of its running speed, it remains cool and increases pump life.
  • The prices are high for this kind of pump.
