Alfa Laval SRU rotary lobe pumps

Alfa Laval SRU rotary lobe pumps are carefully engineered to provide good performance, trouble-free operation and high energy efficiency for demanding applications in the dairy, food, beverage, personal care and pharmaceutical industries.

It is a suitable choice for duties that require contamination-free pumps to meet high standards of hygienic, low-shear, low-pulsation operation. The pump handles both cleaning-in-place and sterilisation-in-place, and can be supplied with thorough documentation to support rigorous validation requirements.

The rotary lobe pumps are designed with features that maximise performance and minimise the risk of contamination. These include a defined compression front cover sealing, rotor nut retention design, drainable pump head and ultraclean surface finishes.

Understanding of flow patterns is vital to ensure high-efficiency fluid transfer with low pulsation, low shear and low noise characteristics. Alfa Laval employs computational fluid dynamics (CFD) to establish exact geometry for the rotors and rotor case.

The product features a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings throughout. It complies with EHEDG, 3-A, 3.1 and FDA hygienic standards and has ATEX approval for use in explosive environments.
