Depend on the Alfa Laval rotary lobe pump for virtually pulsation-free handling of all types of process fluids, no matter the viscosity. Designed for easy maintenance and long service life, these pumps have a wide performance envelope to meet a broad range of process requirements while maximizing uptime and ensuring product quality and plant productivity.
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.
