Rotary positive displacement pump / Lobe pump - Alfa Laval SRU6/260/LS

The Alfa Laval SRU6/260/LS is a robust positive displacement lobe pump designed for the gentle and efficient handling of sensitive process fluids. Engineered in accordance with the most stringent hygienic design standards, the pump features fully validated and effective Cleaning-in-Place (CIP) capability. The SRU pump range is suitable for applications across the dairy, food, beverage, brewing, chemical, pharmaceutical, and home and personal care industries. Its smooth, low-shear pumping principle allows for the handling of products with a wide range of viscosities—from low to very high—including creams, gels, emulsions, aerated mixtures, and media containing delicate cells or organic solids in suspension. Products containing fragile solids, such as curd, can be transferred without damage due to the specially designed tri-lobe stainless steel rotors. The pump has a nominal displacement of 2.60 litres per revolution and a maximum nominal capacity of 93.6 m³/h. Both the inlet and outlet connections are DN100 (4"). The maximum allowable product pressure is 10 bar, with a maximum pump speed of 600 rpm. The maximum permissible spherical solid size is 18 mm. The unit was previously operated in a dairy processing environment for product transfer. It is currently equipped with an 11 kW motor (1.460 rpm, 380/415 V, 50 Hz, 22,5 A). The pump speed is reduced to 472 rpm, resulting in an operating capacity of approximately 70 m³/h. The pump and motor are mounted on a stainless steel frame and fitted with a stainless steel motor cover.
