SX UltraPure
The Alfa Laval SX Ultra Pure rotary lobe pump is specifically designed for gentle movement of process fluids in high-purity applications in the pharmaceutical and biotechnology sectors.
SX UltraPure Rotary Lobe Pump for High-Purity Applications
The SX Ultrapure Rotary Lobe Pump is designed for the moderate transportation of process fluids in high-purity applications spanning the biotechnology, pharmaceutical, home and personal care sectors.
Based on seven different gearboxes, the SX Ultrapure has fourteen distinct pump head displacements to handle flow rates of up to 115 m3/h and differential pressures of up to 15 bar.
Benefit
Sensitivity – the best choice for transporting
The Alfa Laval SX UltraPures multi-lobe rotor shape ensures low pulsation and soft pumping. This makes it the greatest option for transferring sensitive items like blood, plasma, and live cultures, which require delicate handling to avoid shearing and product damage. This EHEDG-approved pump is intended for both cleaning and sterilization in place.
Performance – safeguarding end-product quality
The Alfa Laval SX UltraPure pump is known for its low pulsation, shear, and noise characteristics, as well as its efficient fluid transfer, which improves process repeatability and product quality and yield. This high degree of performance was reached by a thorough understanding of flows, as well as the precise design of the rotors and rotor casing. Alfa Laval uses Computational Fluid Dynamics (CFD).
Improved consumer safety
Alfa Laval SX UltraPure rotary lobe pumps are developed with characteristics that maximize performance while reducing contamination risk. These include a low-profile rotor nut, sanitary front-loading mechanical seals, specified compression front cover sealing, USP Class VI elastomers, a fully drainable pump head with a 3° fall angle, improved surface finishes, and a paintless stainless steel gearbox. Furthermore, the wetted components have complete 3.1 traceability and production transparency, as well as a GDP-compliant Q-Doc documentation package to ensure customer safety.
Cleanability Hand in hand with proving reliability.
The Alfa Laval SX UltraPure pump is a durable, dependable, low-maintenance option that is designed for optimal cleanability and accessibility. Alfa Laval manufactures all pump components, including the rotor casing and high-precision rotors. This simplifies maintenance and ensures complete interchangeability of spare rotor parts.
Heavy-duty shafts, torque locking assemblies, and taper roller bearings are used throughout the sturdy stainless steel gearbox structure to provide reliable operation and low maintenance. The gearbox’s universal design allows the pumps to be mounted with intake and outlet ports in either vertical or horizontal positions.
Global coverage with local presence.
Alfa Laval SX UltraPure rotary lobe pumps come in 14 distinct versions and can handle a wide range of viscosity and temperature requirements, with flow rates of up to 115 m3/h, pressures of up to 15 bar, and temperatures of up to 150°C. A diverse choice of seals is offered to guarantee that the appropriate seal is chosen for the specific application. Standardized for easy specification, worldwide availability, and local support, assuring process repeatability and higher uptime.
Certification, specifications, and standards.
All Alfa Laval SX UltraPure rotary lobe pumps come with the Q-Doc documentation suite to help with qualification, validation, and change control. They meet EHEDG, 3.1, and FDA hygiene standards and are ATEX certified for usage in explosive areas. For more information, please refer to the documents supplied.
Industries
- Pharmaceutical production
- Personal Care
- Biotechnology
Alfa Laval rotary lobe pumps are classic positive displacement pumps that include a rotor case, rotor case cover, rotors, rotor nuts, shafts, gearbox, shaft seals and elastomers. The pump head of the pumps operates without any internal contacting components. The SX Ultrapure can be supplied as a bare shaft pump or installed on a base plate that includes a connection, guard, gear motor and shroud for easy plug-and-play installation. All wet parts are typically built from 316L stainless steel, with a paint-free steel gearbox. Additional goods, as requested, are also available. Alfa Laval also manufactures all pump components, including the very precise rotors and rotor cases. This provides for complete interchangeability of spare rotor parts and simplifies maintenance.
The pump gearbox’s gear train drives the rotors, which are properly synchronized or timed. The contra-rotating propulsion system consists of two rotors that spin in opposite directions within the pump head. Fluid passes through the spaces formed between the rotor’s dwell and the interior of the rotor casing.
Standard design
All media touching steel components, including the rotor case, front cover, rotors, and rotor nuts, employ W. 1.4404 (AISI 316L). The stainless steel gearbox offers maximum shaft rigidity and simple oil seal replacement. The universal gearbox design allows pumps with input and outlet ports to be placed in either a vertical or horizontal plane by adjusting the foot and position, offering flexibility.
With four-lobe rotors certified to 150°C, the conventional Alfa Laval SX Ultrapure can be utilized with CIP and SIP systems more easily.
There are fully interchangeable single, single flushing, and double mechanical shaft seals, as well as fully front-loaded models. The latest technique, which uses stationary and dynamic elastomer seals to prevent pumped media leakage to the atmosphere, controls compression joints using media contacting elastomers.
The Alfa Laval SX Ultrapure is available as a bare shaft pump or mounted on a base plate with couplings, guard, gear motor and shroud for easy plug-in installation.
