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
requirements 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:
HP = (GPM x PSI) / 1440
