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 horse-
power requirements, use the Follow-
ing formula:
Electric HP = (GPM X PSI) / 1460
Gas HP = (GPM X PSI) / 1100
* Engine power varies based on horizontal or
vertical orientation as well as by makes and
model from each manufacturer.
