Alfa Laval SX
Alfa Laval Rotary Lobe Pump SX
Suitable for low, medium and high-viscosity media, the Alfa Laval Rotary Lobe Pumps are the fulfillment of more than 50 years of commitment to rotary lobe pump technology. Their gentle pumping action and reliable performance are the result of continuous development, which is based upon years of experience and carried out at our advanced production and R&D facilities. The Alfa Laval rotary lobe pump portfolio comprises three ranges: SX, SRU and OptiLobe. Each of these is robustly constructed and offers Alfa Laval’s high standards of quality and reliability, and each is positioned for a different type of demand. Collectively, they provide operating economy and high flexibility of use.
Gentle, hygienic design
With their high-precision rotors and low-shear operation, our rotary lobe pumps ensure the gentle movement of delicate products. The pumps offer a number of features that maximize cleanability, and their construction provides compliance with the world’s leading hygienic standards.
Modular pump design
The rotary lobe pumps feature a modular construction. This design feature increases flexibility and reduces spare parts inventory.
Universal mounting
To allow high flexibility when fitting the pump into a production line, all of the rotary lobe pumps can be mounted in either a vertical or horizontal port position (with the exception of the larger SX models).
Improved drainability
All of the rotary lobe pumps can be drained easily when mounted in vertical port position. In the case of the OptiLobe and SX pumps, cusps are retained in vertical configurations for greater efficiency.
Easy seal retrofit
The seals of the rotary lobe pumps are designed for quick and simple up-grading. The broad range of seals includes many seal types and configurations, which can be tailored to your need and application.
Robust gearbox construction
All rotary lobe pumps are fitted with a robust gearbox incorporating heavy-duty taper roller bearings and torque locking assemblies that allow for easy maintenance and high reliability. The pump rotors are driven by a high-precision involute spline drive.
CIP and SIP
All rotary lobe pumps are suitable for use in both Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) applications.
Standards and approvals
All of the rotary lobe pumps are compliant with the EHEDG, 3A and FDA hygienic standards. In addition, the SX and SRU pumps have ATEX approval for use in explosive environments.
Alfa Laval rotary lobe pump SX
The SX is Alfa Laval’s premium rotary lobe pump, designed for use in sensitive and ultra-clean appli-cations. With their optimized pump head geometry and multi-lobe rotors, SX pumps ensure low-shear operation with minimum pulsation. This makes them the best choice for maintaining the integrity of delicate products. SX pumps feature front-loading mechanical seals, as well as a profiled gasket system for the highest level of hygienic sealing. Pump hygiene is further improved by a low-profile rotor nut, which enhances the pump cleanability. Higher surface finishes up to 0.5 Ra are available, as well as electro-polishing and 3.1 material traceability.
