Everything You Need to Know About Pressure Washer Pumps

by Vincent

A pressure washer is sophisticated, too, that enhances the pressure of water coming from a regular hose. The basic principle of a pressure washer is pressure acceleration which is done by the pump.

The pump works as a heart in a pressure washer that receives water from the motor & releases it through a nozzle with higher intensity. In case the pump of your pressure washer burns out or gets damaged, the pressure washer becomes useful.

To purchase a new pump, first, you need to know everything about it. Here we are giving a brief detail about pressure washer pumps from their type to features.

Let’s get started!

Classification of Pumps

A pump is a tool that is used to transport fluids like water. Basically, there are two main categories of pumps that are Centrifugal/cantilever & Positive Displacement pumps.

  • Centrifugal Pumps are divided into three main types based on flow pattern: radial, axial, & mixed.
  • Displacement pumps are of two types: rotatory (gear, cavity, etc.) & reciprocating (plunger, bladder, piston).

The pressure washer pumps belong to a reciprocating class of the second category. Pressure washer pumps are divided into three main types;

  1. Piston (wobble plate)
  2. Axial cam
  3. Plunger (triplex)

1. Piston/Wobble Plate Pumps

Wobble plate is a sub-category of piston pumps. These pumps use the driveshaft to suck up water. It’s one of the most complicated types with only 70% efficiency. You will hardly find these pumps in pressure washers because of the high repair cost.

These pumps can last up to 2-3 years & used in low/medium flow washers.

2. Axial Cam/Swash Plate Pump

Axial cam/swash plate pump is an innovative, less complex form of the piston pump. These pumps use swash plates for water sucking.

Compared with the previous type, the axial cam has a much longer lifespan of approx. 800 hours. These pumps are used in pressure washers with high liquid flow.

3. Plunger Pump

Plunger/crank-driven pump is one of the best, most advanced, but expensive type plunger pumps. With 90% efficiency, these pumps don’t need high maintenance & have a longer lifetime.

Considerable Factors to Choice the Best Pressure Washer

Regardless of the type and efficiency of pumps, you can’t just choose a type and fit that into your washer. Not all the washers are strong enough to bear the advanced-typed pumps that can cause damage to your washer.

Therefore you need to consider various features to buy a pump for your pressure washer. Some of these features are listed below.

  • Pump fluid flow capacity of engine (PSI)
  • Size & orientation of engine shaft (horizontal/vertical)
  • Proper measurement of bold arrangement around the engine
  • Price & maintenance
  • Brand & customer reviews
