Pressure Washer Flow Rate Vs Psi

Getting the job done faster also means saving fuel so not only can a good pressure washer save you time it can also save you money.

Pressure washer flow rate vs psi.

However just because electric models produce less pressure output doesn t mean they re useless. Pressure which is measured in pounds per square inch psi and water flow rate measured in gallons per minute gpm. Psi pound per square inch refers to the amount of pressure created by the equipment. Gas models can produce upwards of 3 000 psi for heavy duty cleaning.

On the contrary this pressure is too less to clean parking areas stained with tar. An electric pressure washer is an ideal unit for smaller projects like cleaning tires grills patio furniture. More water means higher utility bills and ongoing costs in the long run whereas a low water flow rate means more water conserved. The pressure put out by a power washer is measured in psi pounds per square inch and the psi requirements can vary based on what you re aiming to clean.

Pressure washers carry two ratings that reflect their cleaning power. Note that the gpm is just as important as psi when choosing a pressure washer. Electric models usually cap off at 2 600 psi or so. This pressure is more than a garden hose.

An electric power washer is going to have the lowest psi range generally it is between 500 4000 psi with 1 0 4 0 gpm. Pressure washer psi and gpm work together to provide the most efficient cleaning. Kramar told us the sweet spot for an electric washer s pressure in pounds per square inch psi is in the 1 800 to 2 000 psi range a garden hose in contrast is capable of. Gpm gallons per minute also called flow rate is the amount of water delivered by the machine in one minute.

In comparison the 2600g has a flow rate of 2 3 gallons per minute at 2 600 psi giving it a rating of 5 980. For example it ll take a lot less pressure to clean dust and salt from your vehicle than it will take to clean oil stains from your garage floor. It would need somewhere around 4 000 and. Extra heavy duty pressure washers with a psi over 3200 typically have a gpm of around 4 while light duty models may be as low as 1 5.

But a machine with higher ratings will clean much much faster. They are extremely lower maintenance and tend to be fairly quiet. It is said in the pressure washing industry that the pressure psi does the cleaning but the water flow gpm cleans it faster. In general gas pressure washers are much more powerful than electric versions.

For any cleaning job requiring 2 000 psi or less both pressure washers will do a good job getting the material clean but the 2000e will actually get the job done faster despite the fact that it has less power than the other system. The exact or a range of psi required is what the pressure washer psi chart reveals.
