A 25 PSIG minimum inlet pressure is required.
The pump itself can be driven in either direction of rotation; however, the cooling fan
on TEFC motors must always be positioned so that the cooling air is drawn from the
non-drive end of the motor towards the pump.
HORSEPOWER RATINGS: The rating shown are the power requirements for the pump. Gas
engine power outputs must be approximately twice the pump power requirements shown above.
We recommend 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:
Electric HP = (GPM X PSI) / 1460 Gasoline HP = (GPM X PSI) / 1100
