Best Pressure Washer Pumps

Pressure washer pumps play an integral role inside your domestic pressure washers. A pressure washer is a lot less sophisticated and complicated than it sounds. The washer uses a pump, powered by an electric motor, to take in normal running water from a faucet and then squirt it at high speeds through a trigger gun. The pump present inside the washer does the lion’s share of the work and is responsible for adding the pressure to the water flow.

What to Look for When Buying the Best Pressure Washer Pumps?

There are several factors you should consider before buying the right pressure water pump for use inside your home. These factors include:


Flow Rate

The first thing you need to factor in for is the flow rate of your pump. The pump should ideally fill in more than 2 or 3 gallons per minute.


Pressure Levels

Assessing the pressure levels on your pump is also important before the purchase. You should make sure that the pump you buy generates over 2600 PSI of pressure. The more the better!


Material of Construction

You should determine the material of construction to ensure that your pump works well with the viscosity of the liquid you plan to pump. Make sure that the pump does not suffer abrasion or corrosion over the period of use.
