Guardian Boiler Feed

Guardian boiler feed pumps are used to pump condensate and makeup water directly into the boiler(s). Pump action is controlled by a boiler-mounted level controller that senses boiler water-level requirements. Each Guardian boiler feed pump includes a glass water level gauge with sight glass, and it is also equipped with a solenoid makeup valve and reverse-acting float switch to bring in makeup water. Various sizes of carbon steel receivers are available to meet just about any installation requirement.
