Best choice for transporting
With the SXs multi-lobe rotor geometry it offers low pulsation and gentle pumping. This makes it the best choice for transporting sensitive products that require gentle handling to minimize shearing. This EHEDG-approved pump is designed for both Cleaning in Place and Sterilization in Place.
Protecting end-product quality
Low pulsation, low shear and low noise characteristics, while ensuring efficient fluid transfer, are trademarks for the SX pump. This high level of performance has been achieved through a detailed understanding of flows and the exact geometry of the rotors and rotor case. For this Alfa Laval employs Computational Fluid Dynamics (CFD).
Enhanced cleanability
SX rotary lobe pumps are designed with features that maximize performance and minimize the risk of contamination. These include a low-profile rotor nut, hygienic front-loading mechanical seals, defined compression front cover sealing, fully drainable pump head with 3° fall angle, and sanitary or ultra-clean surface finishes.
Cleanability hand-in-hand with low maintenance
Designed for maximum cleanability and ease of access, the SX pump is a low maintenance solution. Alfa Laval manufactures all pump parts, including the rotor case and high-precision rotors. This facilitates maintenance and guarantees full interchangeability of spare rotor parts.
For reliable operation and lower maintenance the robust gearbox construction comes with heavy-duty shafts, torque locking assemblies and taper roller bearings throughout. The gearbox’s universal design provides the flexibility of mounting the pumps with inlet and outlet ports in vertical or horizontal position.

Certification, specification and standards
All SX rotary lobe pumps comply with EHEDG, 3-A, 3.1 and FDA hygienic standards and have ATEX approval for use in explosive environments. For more information, please consult the documentation provided.
Designed for process flexibility, the Alfa Laval Twin Screw Pump is built on a robust, reliable platform that meets stringent hygienic standards. It is capable of handling both product transfer and Cleaning-in-Place (CIP). Its low pulsation characteristics and excellent solids handling capability reduce the risk of product damage, thereby improving product quality. Maintenance is simplified and process uptime increased.
