PULLEY INFORMATION
Pulley selection and pump speed are based on
a 1725 RPM motor and “B” section belts. When
selecting desired GPM, allow for a ±5% tolerance
on pumps output due to variations in pulleys, belts
and motors among manufacturers.
1. Select GPM required, then select appropriate
motor and pump pulley from the same line.
2. The desired pressure is achieved by select-
ing the correct nozzle size that corresponds with
the pump GPM.
HORSEPOWER INFORMATION
Horsepower ratings shown are the power
requirements for the pump. Gas engine power
outputs must be approximately twice the pump
power requirements shown above.
We recommend that a 1.1 service factor be speci-
fied when selecting an electric motor as the power
source. To compute specific pump horsepower
requirements, use the following formula:
HP = (GPM x PSI) / 1450
RPM GPM 3000 PSI 4000 PSI 5000 PSI 5800 PSI
600 5.9 12.1 16.2 20.2 23.4
700 6.8 14.1 18.9 23.6 27.4
800 7.8 16.2 21.6 27.0 31.3
900 8.8 18.2 24.3 30.3 35.2
1000 9.8 20.2 27.0 33.7 39.1
