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.
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).
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.
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.
Available in 14 different models, SX rotary lobe pumps are capable of handling of a wide variety of viscosity and temperature requirements, flow rates up to 115 m3/h, pressures up to 15 bar and temperatures up to 150°C. A wide range of seals is available to ensure that the right seal is selected for the specific application.
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.
