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.

Specifications
Model GP7142
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.
HORSEPOWER INFORMATION
Horsepower ratings shown are the power re-
quirements for the pump. Gas engine power
outputs must be approximately twice the
pump power requirements shown above.
We recommend that a 1.15 service factor be
specified when selecting an electric motor as
the power source. To compute specific pump
horsepower requirements, use the following
formula:
(GPM X PSI) / 1450 = HP
