Optimized investment
High volumetric efficiency and a wide performance envelope often allow for a smaller, more cost-effective pump while ensuring both production capacity and product quality. A broad range, flexible configurations, and compatibility with previous Alfa Laval models simplify pump selection and enable full-port dimensional interchangeability or similar.
Cost-effective operation
High volumetric efficiency enables lower operating speeds, ensuring gentle product handling, increased yield, and low energy consumption. Excellent cleanability and a robust design minimize downtime and increase production efficiency. Compatibility with previous Alfa Laval hygienic rotary lobe pumps enables a simple upgrade path to improved yield, product quality, and lower operating costs.
Enhanced assurance
Fully factory-tested and built on Alfa Laval’s proven rotary lobe technology, MaxiLobe pumps are designed for hygienic applications and offer excellent cleanability and reliable hygienic performance. MaxiLobe is certified by EHEDG- and 3-A, and it complies with FDA regulations. Optional ATEX-compliant models are available for use in explosive atmospheres.
Simpler service
A front-loading seal, fully interchangeable spare parts and easy-to-set pump clearances greatly simplify service. In many cases, the pump can be serviced without removal from the process line, which minimizes downtime and maintenance complexity.
Maximizing flexibility in food and beverage production
See how MaxiLobe pumps maximize flexibility in modern food and beverage production. The exceptional volumetric efficiency allows the same pump to handle media with very different viscosities, making frequent product changeovers simple and efficient.
Ensuring quality in dairy production

Increasing efficiency in home and personal care production
Explore how MaxiLobe pumps increase productivity in home and personal care production. Efficient handling of media with widely varying viscosities, combined with fast cleaning between batches, enables quick turnarounds and maximum utilization of the main mixer.
How MaxiLobe rotary lobe pumps work
Alfa Laval MaxiLobe hygienic rotary lobe pumps are positive displacement pumps that provide smooth, reliable transfer of low- to high-viscosity products while maintaining product integrity.
Inside the pump head, precision-machined rotors rotate in opposite directions without contacting each other or the pump casing. A robust timing gearbox synchronizes the rotors, maintaining precise clearances throughout operation.
As the rotors turn, cavities are created between the rotor lobes and the pump casing. These expanding cavities generate a partial vacuum at the inlet, drawing product into the pump. The product is then gently carried around the outside of the rotors within the cavities. As the rotors mesh on the discharge side, the cavities decrease in size, displacing the product through the outlet at a consistent flow rate.
Because there is no metal-to-metal contact within the pump head, MaxiLobe minimizes product shear and wear while delivering efficient, hygienic fluid transfer. The pump is therefore well suited for handling sensitive, shear-sensitive, and high-viscosity products across a wide range of hygienic processing applications.
Alfa Laval MaxiLobe FAQs
Q. How does MaxiLobe’s volumetric efficiency compare to that of Alfa Laval SRU and SX pumps?
A. In general, the MaxiLobe delivers higher volumetric efficiency than the equivalent Alfa Laval SRU and SX pump sizes. Depending on the duty point, the improvement is most noticeable in low-viscosity and/or high-pressure applications. Accurate comparison requires selecting the appropriate pump size and determining the expected operating speed for your application. Actual performance depends on your specific operating conditions.
Q. Can the MaxiLobe replace the Alfa Laval SRU and SX pumps?
A.The MaxiLobe matches the key porting dimensions of all Alfa Laval SRU pumps and most SX models, enabling replacement with minimal or no modification to existing pipework. To support evaluation and replacement planning, 3D CAD models are available.
Q. Is EN 10204 3.1 material traceability available for MaxiLobe?
A. Yes. EN10204 3.1 material traceability is available as an option.
Q. Is the Alfa Laval knife-edge shaft seal available for the MaxiLobe?
A. Yes. Developed specifically for demanding applications such as chocolate processing, the Alfa Laval knife-edge single shaft seal is available for MaxiLobe sizes 22~63. It requires no external flush media, helping simplify installation and reduce operating costs.
Q. What surface finish options are available for MaxiLobe?
A. MaxiLobe is available with an Ra 0.8 μm surface finish. For enhanced wear resistance, a diffusion hardened surface treatment is available for MaxiLobe sizes 22~73.
Q. Is ATEX certification available?
A. Yes. ATEX certification is available for MaxiLobe sizes 22~73. Alfa Laval can supply both bare-shaft and motorized pumps as ATEX-compliant for Group II, Category 2G, Zone 1 areas.
