How does rotary lobe pumps work?

Alfa Laval rotary lobe pumps consist of two intermeshed rotors affixed to a gear train. A gear train in the pump gearbox drives and accurately synchronizes the rotors. 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.
