Alfa Laval OptiLobe Series (Rotary Lobe Pump)
Alfa Laval OptiLobe, Rotary Lobe Pump
Alfa Laval’s OptiLobe is an optimized rotary lobe pump that is a cost-effective alternative to Alfa Laval SRU and SX rotary lobe pumps. Designed for standard duties within the food, dairy and beverage industries.
Simplicity of installation, operation, and maintenance are hallmarks of the OptiLobe series, Alfa Laval’s basic rotary lobe pump. Universal mounting with inlet and outlet ports in vertical or horizontal position makes installation very simple. Operation is just as straightforward and reliable, thanks to the robust gearbox construction. Besides that, the fully interchangeable front-loading seals provide fast access for inspection or replacement without pipe work disassembly.
Alfa Laval’s OptiLobe is fully 3-A compliant and EHEDG certified. All product contact components are FDA compliant as well.

Simplicity at its best
Simplicity of installation, operation and maintenance are hallmarks of the OptiLobe, Alfa Laval’s basic rotary lobe pump. Universal mounting with inlet and outlet ports in vertical or horizontal position makes installation very simple.
Operation is just as straightforward and reliable thanks to the robust gearbox construction. Fully interchangeable front-loading seals provide fast access for inspection or replacement without pipe work disassembly.
Solid product quality
The OptiLobe offers reliable fluid transfer and gentle product handling in combination with low pulsation, low shear and low noise characteristics. The pump is suitable for most general application as well as for Cleaning-in-Place.
Low total cost of ownership
The OptiLobe not only reduces your initial capital investment but also reduces total cost of ownership. The simple, robust low maintenance design provides quick return on investment.
Robust construction
The OptiLobe features a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings throughout. This delivers reliable operation and reduces maintenance.
Application
Alfa Laval’s OptiLobe range of rotary lobe pumps combines cost-effective simplicity with Alfa Laval quality and reliability. It’s been developed for general applications within the dairy, beverage, and food industries. Ideal for CIP operation, OptiLobe is fully 3-A compliant and European Hygienic Equipment Design Group (EHEDG) certified. All product contact components are Food and Drug Administration (FDA) compliant as well. OptiLobe features front loading seals which allows quick and easy inspection or seal replacement without rotor case removal. With a compact design, it’s an efficient PD pump capable of flow rates up to 211 US gallons/minute and pressures up to 115 psi.

The robust gearbox construction with heavy-duty shafts, torque locking assemblies, and taper roller bearings throughout delivers reliable operation and reduces maintenance. The pump is suitable for most general applications and is clean-in-place (CIP) capable. The low maintenance design provides a quick return on investment.The OptiLobe not only reduces initial capital investment, but also reduces total cost of ownership (TCO).
Working Principle
The positive displacement of the OptiLobe pump is provided by non-contacting, counter rotating tri-lobe rotors within a fully swept pump chamber. All OptiLobe pumps are capable of reversing flow without modification, as demonstrated in the graphic below.
Operating principle
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.
Construction
Alfa Laval rotary lobe pumps are positive displacement pumps with rotor case, rotor case cover, rotors, rotor nuts, shafts, gearbox and shaft seals and elastomers. The pumps operate with no internal contacting parts in the pump head.
The OptiLobe can be supplied either as a bare shaft pump or mounted on a base plate complete with coupling, guard, gear motor and shroud for easy plug-and-play installation.
The standard materials of construction are 316L stainless steel for all wetted parts, all stainless steel exterior and EPDM for all product-wetted elastomers. EasyFit shaft seals are fully front loading and fully interchangeable.
In addition, Alfa Laval manufactures all pump parts, including the rotor case and high-precision rotors. This facilitates maintenance and results in full interchange ability of spare parts.
Pump range
OptiLobe rotary lobe pumps are available with six different pump head displacements based upon 3 different gearbox modules., flow rates up to 48 m3/h, differential pressures up to 8 bar, temperatures up to 130°C and port sizes from 40 to 80 mm in diameter.
Higher profits and lower maintenance costs with OptiLobe rotary lobe pump
Italian food group Parmalat SpA set out to increase operating efficiencies and reduce maintenance through the introduction of new technology. Replacing a progressive cavity pump with an Alfa Laval OptiLobe rotary lobe pump boosted both productivity and profits.
This straightforward hygienic pump meets or exceeds all the characteristics of a progressive cavity pump, including minimal shear, variable viscosity handling and the ability to move a variety of viscous media at lower velocities.
