Alfa Laval’s SRU rotary lobe pumps are suitable for industries such as dairy, food, beverage, personal care and pharmaceuticals, which 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 documentation to support validation requirements.
Features designed to maximise performance and minimise contamination risk include a defined compression front cover sealing, rotor nut retention design, drainable pump head and ultraclean surface finishes.
To ensure high-efficiency fluid transfer with low pulsation, low shear and low noise characteristics, the company employs computational fluid dynamics (CFD) to establish exact geometry for the rotors and rotor case.
The pumps have a robust gearbox construction with heavy-duty shafts, torque locking assemblies and taper roller bearings throughout. They comply with EHEDG, 3-A, 3.1 and FDA hygienic standards and have ATEX approval for use in explosive environments.
