PDBF-Series Positive Displacement Vacuum/Boiler Feed

The Skidmore PDBF Displacement Vacuum pumps produce a powerful vacuum using Liquid-Ring pumps that helps reduce heating costs, minimize heat loss, and operate boilers at lower pressures!

PDBF-Series Positive Displacement Vacuum/Boiler Feed

The Skidmore PDBF-Series are designed to pump condensate and makeup water directly into the boiler(s) using various pressures and flows specifically tailored to boiler specifications. The PDBF-Series is available with Cast Iron or 3/8” thick Carbon Steel receivers, with a broad range of size options. 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 fees 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. These Liquid-Ring Vacuum pumps feature close-coupled design, cavitation protection, Totally Enclosed Fan Cool motors, and standard mechanical seals capable of handling temperatures up to 250 degrees F.
