Alfa Laval SRU rotary lobe pumps have been engineered to provide reliable performance, trouble-free operation and good energy efficiency for demanding applications in the dairy, food and beverage sectors.

The pumps are designed especially for duties that require contamination-free pumps to meet high standards of hygiene, low-shear and low-pulsation operation. The pumps handle both cleaning-in-place and sterilisation-in-place requirements.

Contamination is minimised, thanks to a defined compression front cover sealing, rotor nut retention design, drainable pump head and clean surface finishes.

Understanding of flow patterns is vital to ensure high efficiency fluid transfer with low pulsation, low shear and low noise characteristics. To this end, Alfa Laval has used computational fluid dynamics to establish the exact geometry for the rotors and rotor case.

For reliable operation and low maintenance, the SRU has a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings.
