Alfa Laval OptiLobe Series Pumps
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. Fully interchangeable front-loading seals provide fast access for inspection or replacement without pipe work disassembly.
OptiLobe is fully 3-A compliant and EHEDG certified. All product contact components are FDA compliant as well.

Alfa Laval is a leading global supplier of products and solutions within the key technology areas of heat transfer, separation, and fluid handling.
APPLICATION
The 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.
PRODUCT QUALITY
The OptiLobe offers reliable fluid transfer and gentle product handling in combination with low pulsation, low shear, and low noise characteristics. 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.
Standard Design
PUMP GEARBOX
The OptiLobe pump range has a universal gearbox design with the flexibility of mounting inlet and outlet ports in either a vertical or horizontal plane by simply changing the foot position. A stainless steel gear canister bearing housing provides a clean, paint-free, and corrosion-resistant external finish.
PUMP HEAD CONSTRUCTION
The pump head is designed with full bore inlet and outlet ports, maximizing port efficiency and net positive suction head (NPSH) characteristics. Each pump is fitted with tri-lobe rotors and rated to 266°F.
STANDARD SPECIFICATION OPTIONS
- Specification of inlet and outlet ports (complete with Tri-Clamp® connections)
- Available in bare shaft pump only
SHAFT SEAL OPTIONS
EasyFit type single or single flush/quench mechanical seals are available.
All seals are designed as front-loading, self-setting, and self-adjusting for fast on-site seal changeability. Specialized mechanical seal setting is not required as the seal is dimensionally set on assembly.
