JVBF Series Boiler Feed

JV 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. JVBF Series Vacuum/Boiler Feed units 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 on receivers designed to replenish water inside the boiler feeds unit when water levels get too low. The water passes through a Venturi, creating a powerful vacuum that aids in air removal from the system and allows steam to travel long runs.
