HIGH PRESSURE NOZZLES
Most operators of pressure washers are not aware
of the inportance of nozzle orifice size. The size of the nozzle
determines if your pressure washer is developing the correct
pressure. If the nozzle size is to small it will restrict the
flow and the unloader valve will go into bypass. If the nozzle
is to large it will not restrict the water flow enough and the
pressure at the nozzle will drop. In fact if you have a pressure
washer with an unloader valve that is not adjustable you can
lower the pressure by using a larger nozzle than the machine
calls for. The degrees of the nozzle pertains to the spray fan
generated by the nozzle. A zero degree spray tip sprays a small
circular pattern such as a pencil tip. A 40 degree tip will
spray a fan that has a 40 degree width. There is a formula used
to determine the nozzle size and charts are available using
this formula. However nozzles wear fairly quickly and the size
stamped on the nozzle will no longer apply. The best way to
determine if your nozzle is correct is to insert a gauge with
quick coupler ends into the line on the output side of the unloader
valve. If your machine is not putting out the proper pressure
and the pump is operating to specifications change the nozzle
size to a larger or smaller orifice size until the gauge reads
the pressure your machine is rated to. |

- In the top Blue row find your machines
PSI (pressure per square inch). Use the closest PSI that is in
the chart.
- In the column below your machines PSI find your machines GPM
(gallons Per Minute in Red. Use the
closest GPM that is in the chart.
- When you find the row your GPM (gallons per minute) is located
in follow that row over to the LEFT hand Green
column to determine your correct nozzle size.
