Alfa Laval OptiLobe Rotary Lobe Pump


Alfa Laval OptiLobe rotary lobe pumps are cost-effective alternatives for general applications requiring delicate product handling and simple serviceability. Versatile, reliable and energy-efficient, these food grade sanitary positive displacement pumps enhance both process flexibility and operational reliability. 

  • Gentle low-shear operation ensures product integrity
  • Stress-free maintenance due to self-setting, front-loading seals
  • Cost effective sanitary pump
  • Process flexibility


Count on corrosion-resistant, all stainless-steel Alfa Laval OptiLobe rotary lobe pumps to maximize process flexibility, minimize the risk of contamination and make washdown simple. Engineered for use within the food, dairy, beverage, and home and personal care industries, these positive displacement pumps conform to CE directives and EHEDG, 3-A and FDA hygienic standards.


The Alfa Laval OptiLobe Rotary Lobe Pump has a strong platform, advanced seal design and heavy-duty, long-life bearings which add up to more uptime and boosted productivity. It also features front-loading, self-setting seals with seal faces directly in contact with the media ensures superior cleanability and lubrication, resulting in improved seal life. With shaft support made of a solid one-piece bearing housing and heavy-duty L10 tapered roller bearings the OptiLobe has 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. Alfa Laval’s OptiLobe has 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.

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.
