Model LP301A-0081 Specifications
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 mo-
tors 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
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:
HP = (GPM X PSI) / 1450
