Consult the factory for special requirements that must be met if the pump is
to operate beyond one or more of the limits specified above.
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 selecting 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 approxi-
mately twice the pump power requirements shown above.
We recommend that a 1.1 service factor be specified when
selecting an electric motor as the power source. To compute
specific pump horsepower requirements, use the following
formula:
(GPH X PSI) / 1440 = HP
