How does rotary lobe pumps work? Alfa Laval rotary lobe pumps, a leading choice among rotary pump types, consist of two intermeshed rotors affixed to a gear train. The gear train in the pump gearbox drives and accurately synchronizes the rotors, which is a key feature of positive displacement pumps. The rotors move in opposite directions, creating a partial vacuum that allows atmospheric pressure or other external pressures to force the fluid into the pump chamber. As the rotors disengage, a cavity forms and expands, filling with fluid. As the rotors engage, the cavity diminishes, displacing the fluid into the outlet port. Alfa Laval rotary lobe pump applications include transferring sensitive fluids and supporting hygienic processes in various industries.
