Take advantage of these technological features that enable Alfa Laval OptiLobe rotary lobe pumps add value to your processes. 

• A robust platform, advanced seal design and heavy-duty, long-life bearings contribute to more uptime and higher productivity. 

• Truly front-loading, self-setting seals with seal faces directly in contact with the media ensures superior cleanability and lubrication, improving seal life. 

• Shaft support made of a rigid 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, thereby reducing the risk of pump head contact whilst decreasing maintenance requirements and increasing uptime.
• Optional 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.

OptiLobe rotary lobe pumps are available with 10 different pump head displacements based on five different gearbox modules, flow rates up to 77 m³/h, differential pressures up to 8 bar, media temperatures up to 130°C and port size from 25 to 100 mm in diameter.

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

 The movement of the counter-rotating rotors creates a partial vacuum that allows 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.

Part of the company’s rotary lobe pump range, the Alfa Laval OptiLobe is carefully engineered to provide reliable process performance, trouble-free operation and good energy efficiency in demanding applications. Alfa Laval provides a comprehensive range of hygienic pump technologies and specifications to meet customer demands with regard to preserving product quality, process efficiency, and easy maintenance.
