Drip-proof motors

Fire pump motors are the critical component in building sprinkler systems, their role being to supply a robust, pressurised water supply to both the sprinkler risers and to hose stand pipes distributed throughout the building.

Marathon's new TEFC fire pump motor is available in a power range of 3HP to 450HP, with two- and four-pole capabilities, three-phase, 1800rpm to 3600rpm, 200V to 460V and 60/50 Hz ratings. It is of cast-iron construction, and uses ball bearings to provide a robust and reliable unit.
