A fire pump electric motor is a three-phase induction motor that drives electric fire pumps. Motors designed for fire pump service meet NFPA 20 requirements and are offered UL listed. When selecting an electric fire pump motor, power, speed, supply voltage and the starting method of the controller are evaluated together.
Marathon TEFC (totally enclosed, fan cooled) fire pump motors are manufactured in a 3 – 450 HP power range with 2 or 4 poles. A cast iron frame, ball bearings and standard red paint are the motor's key features. The motors operate with a 1.15 service factor at 40 °C ambient temperature.
The motors have a NEMA Design B, code G or lower design and meet EISA 2007 efficiency requirements. The 12-lead construction allows wye-delta, across-the-line or part-winding starting, so the motor can be used with controllers using different starting methods. They are offered at 60/50 Hz ratings with C-flange, D-flange and P-base mounting options.
Marathon fire pump motors are listed under UL File EX5190 and CSA File LR2025. Fire pump electric motors can also be supplied under the OMEC, WEG and Techtop brands.
