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.
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
Horsepower ratings shown are the power require- ments for the pump. Gas engine power outputs must be approximately twice the pump power require- ments shown above.
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:
GPM X PSI =hp 1450
