We Sell, Install and Service All Brands
We sell and service all of the most popular UL-Listed fire and jockey pump controllers. And when it comes to turnkey replacements of existing controllers, nobody is more experienced and qualified. We are certified by all the manufacturers of UL-Listed and FM Approved fire pump controllers to sell, install, commission, and service their systems.
Controllers are the most complex, and troublesome, part of fire pump systems, serving as the brain of the system. Our service technicians receive extensive training on the many controller brands and start types. Our engineers are recognized as industry experts on all matters pertaining to controllers. You can count on our team of engineers and techs to serve as your one-stop source for advice, repairs and replacements of fire and jockey pump controllers.
Most Popular Controller Start Types
Across the Line
Initially connects motor directly to full power, similar to flipping a switch.
Wye-Delta Open Transition
Starts motor with its wye (start) windings connected, then controller reconnects to the motor’s delta (run) winding. This is a two-step process, which usually takes 2 to 3 seconds, and momentarily disconnects from the motor during the transition.
Wye-Delta Closed Transition
Starts motor with its wye (start) windings connected, then controller reconnects to the motor’s delta (run) winding. This is a two-step process, which usually takes 2 to 3 seconds without disconnecting from the motor during the transition.
Uses an autotransformer in the controller to step up the voltage applied to the motor.
Starts motor with only part of the motor’s winding connected, and then during closed transition, adds remainder for running it.
Uses a special solid state soft start module to control current and voltage to motor. This closed transition process take 3 to 5 seconds.
NOTE: Power starting curves show approximations of percentages of rated full load current. Actual results will depend on the controller make and model, voltage, and motor HP.
