OptiLobe Pump Technology


Add value to your process with these technological features of the Alfa Laval OptiLobe.


  • A strong platform, advanced seal design and heavy-duty, long-life bearings add up to more uptime and boosted productivity.
  • Front-loading, self-setting seals with seal faces directly in contact with the media ensures superior cleanability and lubrication, resulting in improved seal life.
  • Shaft support made of a solid one-piece bearing housing and heavy-duty L10 tapered roller bearings with a minimum life of 20,000 hours. This contributes to stable shaft retention and more balanced loading, reducing the risk of pump head contact while decreasing maintenance needs and maximizing uptime.
  • Available heating/cooling front covers for processes, such as sugar solutions, butter and margarines, marmalades, body butters, gels and lotions, where products tend to harden at low temperatures.


How OptiLobe Works: Operating Principles      


A gear train in the pump gearbox drives the rotors and provides precise synchronization of the tri-lobe rotors.


The motion of the counter-rotating rotors creates a partial vacuum that permits atmospheric pressure or other external pressures to force fluid into the pump chamber. As the rotors revolve, an expanding cavity forms, filling with fluid. As the blades disengage, each dwell forms a cavity. As the rotor blades engage, the cavity diminishes and fluid is, displaced into the outlet port.
