PDBF Series Boiler Feed

PD Series units produce a powerful vacuum that allows boilers to operate at a lower pressure, minimizing heat loss and reducing heating costs. Units are available in simplex, semi-duplex, and duplex models. PDBF Series Positive Displacement Vacuum/Boiler Feed units are designed to pump condensate and makeup water directly into the boiler(s) using various pressures and flows specifically tailored to boiler specifications. Pumping action is determined by a boiler-mounted level controller and offers standard float-operated makeup valves or special electric solenoid valves on receivers designed to replenish water inside the boiler feed unit when water levels get too low. Liquid-ring Vacuum pumps come with durable impellers designed for smooth and efficient water passage and produce a liquid seal in the water tank when running.
