Pressure Washer Flow Rate

Jetter and pressure washer nozzle calculator sizing chart.

Pressure washer flow rate.

The bar is the energy with which the water will hit the surface you are cleaning. Psi nozzle size orifice calculate the pressure required. But a machine with higher ratings will clean much much faster. Flow rate flow rate is measured in litres.

So that is 50 gallons with the water hose vs. An average garden hose allows water to flow at a rate of 5 10 gpm gallon per minute at a pressure of 30 50 psi pounds per square inch. Even if the gpm water flow of your water supply is just a little bit lower than the gpm specs of the pressure washer you can wind up ruining the unit. Calculate the nozzle size required.

Gpm gallons per minute also called flow rate is the amount of water delivered by the machine in one minute. So let s take for example two different pressure washers the goodway hpw 2000 e electric pressure washer and the hpw 2600 g gas powered unit. Power a pressure washer s power is measured in watts.

The faster the flow rate the quicker the water comes out. A machine with lower ratings can do almost all the jobs a more powerful machine can do. 12 gallons with the pressure washer. Higher pressure is best for tough jobs while light jobs.

And the pressure washer actually got the drive way cleaner gotta love technology pressure washer gpm vs psi. Pressure washers carry two ratings that reflect their cleaning power. This gives the pressure washer between 5 18 times more cleaning power using 68 less water. The gpm number on the pressure washer has to match the capacity or the pressure of the water supply.

More watts equal more power. Pressure which is measured in pounds per square inch psi and water flow rate measured in gallons per minute gpm. The first has a flow rate of 3 5 gallons per minute at a pressure of 2 000 psi giving it a rating of 7 000. A light duty residential pressure washer uses 1 6 gpm at a pressure of 1750 psi.

Pressure rated bar is the average pressure a pressure washer will reach while you use it. Basically the higher the two numbers on your pressure washer rating the more powerful the machine you have. Most consumer pressure washers require a feed at typical municipal pressure and at a flow rate of more than the washer s output.
