Technical Support
Always remember that when replacing a general purpose, or self cooled motors,
such as a pump motor, to consider Service Factor (SF). Service Factor is a multiplier.
Multiplying the Service Factor times the nameplate horsepower of the motor
provides the available range of horse power. For example, a 1 horsepower motor
with a 1.15 Service Factor can safely operate a 1.15 horsepower load, i.e., 1 x 1.15
= 1.15. A 1 horsepower motor with a 1.40 Service Factor can safely operate a 1.4
horsepower load, i.e., 1 x 1.40 = 1.4.
