H Series Boiler Feed

An elevated receiver unit using horizontal pumps, H Series pumping systems are available in simplex, duplex, triplex, or quadruplex configurations from 1,000 to 125,000 sq. ft. equivalent direct radiation or 7.5 to 1,000 boiler horsepower. H Series Boiler Feed units can pump condensate and makeup water directly into the boiler(s) using various pressures and flows. Pumping action is determined by a boiler-mounted level controller that senses boiler water level requirements. We offer standard float-operated makeup valves or special electric solenoid valves that are designed to replenish water inside the boiler feed unit when water levels get too low. Attached horizontal pump(s) sit beneath an elevated receiver on a structural steel base.
