The Alfa Laval SRU rotary lobe pump is a positive displacement pump for gentle handling of sensitive process fluids in demanding hygienic applications. High-precision rotors and low-shear, low-pulsation pumping action ensure reliable, continuous performance and superior energy efficiency. Its contamination-proof design ensures compliance with the most stringent hygienic design standards and the requirements for Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) validation.
High pump efficiency and gentle product treatment optimize contamination-free transfer of viscous products
- Maximize uptime through consistent performance
- Raise product quality due to gentle, low-shear product handling
- Increase product safety and quality due to hygienic design and validated cleaning processes
- Add more process flexibility with versatile handling and efficient pumping of various products, including viscous media
- Low-maintenance design – a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings minimizes service
The Alfa Laval SRU rotary lobe pump provides high-efficiency fluid transfer, maximizing uptime while minimizing contamination risks and maintenance costs. Its low-pulsation, low-shear pumping action transfers media of varying viscosities with ease. Modular design provides great flexibility to tailor a pump to meet specific process requirements.
Available with 12 different pump head displacements, the SRU rotary lobe pump handles flow rates up to 106 m3/h, differential pressures up to 20 bar and temperatures up to 200°C.
How does the SRU rotary lobe pump work?
