Variable speed fire pump controller

A Variable Speed (VFD) Fire Pump Controller is a fire pump controller that is able to vary the speed of the motor depending on the demand of the fire pump, resulting in the ability to hold a constant discharge pressure. It differs from other industrial variable speed control devices because it is now considered a life safety device, and so must adhere to the more rigid standards set forth by NFPA-20.
