Features to minimize the risk of contamination — including a defined compression front cover sealing, rotor nut retention design, drainable pump head and ultra-clean surface finishes — are the reason that Alfa Laval asserts its SRU rotary lobe pumps offer reliable performance, trouble-free operation and energy efficiency in dairy, food, beverage and pharmaceutical applications.

According to the company, the pumps can be used for applications that require contamination-free pumps to meet high standards of hygiene, low-shear and low-pulsation operation. This pump, which complies with EHEDG, 3-A, 3.1 and FDA hygienic standards and has ATEX approval for use in explosive environments, handles both cleaning-in-place and sterilization-in-place.
