Rotary lobe pumps

Boerger's Rotary Lobe Pumps are self-priming, valve-less, reversible, positive-displacement pumps ideal for permeation and back-pulse applications with membrane bioreactors (MBRs). The reversibility of the pump unit reduces the amount of valves, pipes and programming. It is ideal for MBR processes because of wide flow ranges and ratios, as well as handling of low NPSHa (varying transmembrane pressures [TMPs] of the submerged membranes during permeation), allowing large amounts of entrained air in the permeate.Boerger www.boerger.com Visit Boerger at WEFTEC.14 - Booth 4234
