Rotary lobe pumps SX UltraPure

The SX UltraPure Rotary Lobe Pump is designed for gentle transportation of process fluids in high-purity applications across the biotechnology, pharmaceutical, and home and personal care industries.
The SX UltraPure is available with 14 different pump head displacements based on seven different gearbox modules to handle flow rates up to 115 m3/h and differential pressures up to 15 bar.

Benefits
• Low pulsation and very gentle pumping, making the pump ideal for sensitive products.
• Minimized shearing to protect end-product quality.
• Low maintenance, increased process uptime.
• Low contamination risk due to full material traceability and USP Class VI elastomers that reduce the risk of process contamination from extractables.
• Smooth qualification, validation and process control: material traceability, and pump supplied with the Alfa Laval Q-doc package in line with Good Documentation Practices.

All media contacting steel components, like the rotor case, front cover, rotors and rotor nuts, are in W. 1.4404 (AISI 316L). The stainless steel gearbox provides maximum shaft rigidity and easy oil seal replacement. The gearbox design is universal, which enables the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane by changing the foot and its position. The standard Alfa Laval SX UltraPure has four-lobe rotors rated to 150°C, facilitating use with CIP and SIP processes. Fully front-loading and fully interchangeable single, single flushed and double mechanical shaft seals are available. All media contacting elastomers are controlled compression joints, the latest technology where static and dynamic elastomer seals are used to prevent leakage of pumped media to the atmosphere. The Alfa Laval SX UltraPure can be supplied either as a bare shaft pump or mounted on a base plate complete with coupling, guard, gear motor and shroud for easy, plug-and-play installation.
