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

We recommend that a 1.1 service factor be specified when s electing an electric motor as the power source. To compute specific pump horsepower requirements, use the following formula:

HP = (GPM X PSI) / 1440

Pump speeds of 640 RPM and above require a minimum inlet pressure of 12 psig. Pump speeds of 805 RPM and above require a minimum inlet pressure of 14 psig.
