Have you tried using soap, water, and scouring chemicals to clean a surface, but it still won’t come out clean? It’s time to try a pressure washer.

The best pressure washer pump works to ensure you get sparkling and spotless surfaces when you clean.

Pressure washers work by releasing jets of water under very high pressure. The force of water is highly effective in breaking down ground-on dirt that won’t budge under normal cleaning conditions.

However, the pressure will cause no damage to the surface you’re cleaning.

A pressure washer comes with many parts, and one of them is the pump. Without it, the machine would not be able to achieve its cleaning objectives.

The pump helps water accelerate to a high pressure as it squirts from a hose through a trigger gun.

Using a pressure washer, especially for hard-to-clean projects, makes your work a lot easier.

However, without the best pressure washer pump, you might not be able to get the results you desire. It’s for this reason that you must invest time in finding the most appropriate pump for your washer.

Types of Pressure Washer Pumps

Pressure washer pumps are classified according to how they work. They fall into three main types: wobble, axial, and triplex.

However, there are two broader categories: rotary and reciprocating types. The rotary type uses piston and plungers, while the reciprocating types use gears, screws, and vanes.

In this section, however, we’ll cover the three main types as they’re easier to understand for typical consumers.

So, if you’re wondering what category to pick for your new pump, here is what you should know.

1. Wobble Pumps

Most entry-level pumps use a wobble plate connected to the drive shaft.

It works by pushing pistons back and forth to create suction and then push the water out. Each piston has a large spring that allows the wobble plate to push against them.

This design reduces the efficiency of the pump to only 70% as it has to push against water and springs.

Wobble pumps are hard to repair as they have many intricate parts in hard-to-reach places. Their life span is about 2-3 years.

Advantages of Wobbler pumps are:

  • They can run dry
  • Are self-priming
  • Produce high pressure

On their downside, they can’t be repaired when spoilt and must be replaced. This type is best used in washers below 2500 PSI and a flow rate of less than 2 GPM.

2. Axial Cam Pumps

This is an intermediate level pump that comes with more advantages than the wobble pump.

It’s capable of higher GPM and PSI. The difference in design is that the pistons rotate around the swashplate.

As they do so, the swashplate angle causes them to stroke. They go from one side to suck water and the other to push it out.

The movement allows for a larger oil reservoir and larger bearings, extending life.

The lifespan of the pump is twice or thrice that of wobble pumps. They’re used in washers with less than 3500 PSI.

Their benefits are

  • Longer life than other pump types
  • More efficient than the wobble type
  • You can adjust the pressure of water and how it flows

However, the pump becomes very hot while in use. It can also cause excessive vibration if not well balanced.

3. Triplex Plunger Pump

These are professional pumps that allow for higher pressure and last longer than the previous two.

They use the mechanism of a car engine to drive positive action pistons to suck in water. They then push out water with each stroke.

They work at 90% efficiency as the pistons stroke 120 degrees apart for a smooth flow.

Their lifespan depends on how well you maintain them. They’re used in machines with a PSI higher than 3000 PSI.

The reasons you may consider this type of pump are

  • The pumps are highly efficient
  • Less prone to leakages
  • Excellent tolerance to high pressure

On their downside, they’re quite expensive.

  1. A pump can increase the speed of water flow to wash floors, decks, garden, lobby, garages, vehicles, boats and so on. It is more beneficial than cleaning or washing them manually.
