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

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
