applies to gas or diesel
and Hydraulic Powered Pressure Washers.
Pressure Washer motors have a fixed speed, matched to your pump.
If you are replacing a pump or electric motor make sure you know
the rated speed of your drive or pump.
all gas motors run at 3400 to 3500 RPM. If you have a direct drive pump
it is designed to run at this speed.
Most belt or gear driven pumps run
at 900 to 1750 RPM, but the gas engine still runs at 3400. Pulley sizes or
gearing reduces the pump RPM to it's particular operating speed.
Modern small diesel engines built
for the pressure wash industry are designed to run at 3400 RPM
while more expensive, larger diesels run at slower speeds.
If you are not sure, check with the engine manufacturer.
powered pressure washer speed is a little more complicated.
The speed of the hydraulic motor is controlled by the pressure and
flow of the hydraulic oil supply.
Hydraulic Pressure Washers have a pressure compensated flow
control which compensates for various oil gpm/psi. If you

Whatever you do, don't over-speed
the pump. This will, at best, break your pump. At worst, it
will damage you or someone around you.
