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% toler-
ance on pumps output due to variations in
pulleys, belts and motors among manufactur-
ers.
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
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:
HP = (GPM X PSI) / 1440
