TYPICAL PRESSURE WASHER SYSTEM
DESIGNING YOUR SYSTEM
Pump selection
The heart of any pressure washer system is
your Aussie Pumps >Big Berty= Bertolini pump.
Choose the pump that=s right for your work
demands. Higher pressure is not necessarily
best. To much pressure and flow will cause
unnecessary wear on your pressure system.
In addition, damage to the objects and
surfaces to be cleaned could result.
Never exceed the maximum pressures or
rotation speed stated in the Technical Data.
Refer to the Technical Data for the correct rpm
required.
Motor/engine Selection
The size of the motor required is determined
by the flow (litres/minute) and the pressure
(bar/psi) desired.
Ensure that a petrol engine runs fast enough to
supply the required horsepower but do not
exceed the engine manufacturer=s
specifications.
Consult pump and engine manufacturer=s
technical guidelines.
DRIVE SYSTEM
There are three common methods of driving or
connecting the pump and motor/engine. Direct
drive and gear reduction drive require special
components that are matched to the pump and
to the motor/engine as well as other technical
considerations. The third is belt drive. Belt
drive is considered inefficient (belt slip) and can
have negative OH&S ramifications.
