The HLR pump is a rotary lobe pump designed in compliance with the EHEDG specifications for plants and processes that comply with the strictest hygienic requirements. Due to the low working speed, the rotary lobe pump is characterised by a gentle pumping and low shear of the product causing less damage possible. The rotary lobe pump is an ideal pump for the transfer of all types of liquids (from 1 to 1.000.000 cP) and liquids with solid particles (curd, biologic cultivations, etc.). The rotary lobe pump is adequate for the food-processing, cosmetic and pharmaceutical industries The HLR rotary lobe pump basically consists of two lobe rotors which rotate inside the casing without touching each other. As the rotors rotate, the space between the lobes and the casing is successively filled with the product which is driven to the discharge nozzle displacing a fixed amount of product. The pumped product forms a continous stream due to the adjusted tolerances of the lobes and the pump casing thus ensuring an efficient pumping. Vertical support. Bare-shaft construction. Self-drainable pump. Tri-lobe rotors. Hygienic design of the attachment of the lobes. Sanitary mechanical seal, internal assembly. The seal is disassembled from the frontal part without disassembling the casing of the pump. Gaskets with deformation limiters prevent any dead leg. Easy cleaning and maintenance. Standard connection: clamp. Pump certified according to the EHEDG standards. Materials Investment casting casing and lobes: AISI 316L Ball bearing support GG-25 Gaskets: EPDM according to FDA 177.2600 Mechanisal seal: SiC/C/EPDM Internal surface finish: Ra ≤ 0,8µm External surface finish: bright polish Options Mechanical seal: SiC/SiC, TuC/SiC. Flushed or balanced mechanical seal. Gaskets: FPM or FFPM. Bi-wing lobes. Relief valve or external by-pass. Heating jacket. Ra ≤ 0,5 μm surface finish for pharmaceutical applications. Horizontal assembly (no EHEDG certificate). Various types of drives and protections (gear motor with frequency converter, etc.). Assembly on a 304 stainless steel baseplate on silent-blocks, sanitary design. Trolley and control panel. Connections: Clamp DIN32676, DIN 11864-1, DIN 11864-2, etc. Material certificates (3.1), roughness certificate. The pump can be ATEX certified.

The Rotary Lobe Pumps from Alfa Laval are able to handle low, medium and high viscosity media, these pumps are used where gentle, sanitary processing is a requirement. Application The SRU range of rotary lobe pumps has been designed for use on wide ranging applications within the Brewing, Dairy, Food, Pharmaceutical and Chemical industries. The SRU pump can handle from low to high viscosity media and is suitable for CIP (Cleaning In Place) and conforms to USA 3A Sanitary Standard. The characteristic smooth, low shear pumping action is ideal for products such as creams, gels, emulsions, aerated mixtures, and delicate cells and organic solids in suspension. The SRU range is compact in size and highly efficient, capable of flow rates up to 106 m³/h and pressures up to 20 bar. The new improved modular design provides for greater application flexibility and cost effective easy maintenance. Standard Design Pump Gearbox The SRU pump with its conventional lobe pump design concept has a robust cast iron gearbox, which provides maximum shaft rigidity and easy oil seal replacement. The SRU range in series 1-4 has a universal gearbox design. This gives the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane by changing the foot position. The SRU range in series 5 & 6 has dedicated gearbox castings, which also allows the inlet and outlet ports to be in either the vertical or horizontal plane. A quality epoxy paint system is used on the gearbox exterior for optimum protection against natural and corrosive elements. Pumphead Construction The SRU in standard specification has sanitary design full bore inlet and outlet ports to International Standards, maximising inlet and outlet port efficiency and NPSH characteristics. Enlarged diameter and rectangular ports are also available to handle high viscosity products. The SRU in standard specification has tri-lobe rotors with the option of bi-lobe rotors for handling fluids containing large delicate solids. All rotors are available in three temperature ratings allowing the pump to be operated at maximum process temperatures of 70°C, 130°C and 200°C for both fluid pumped and CIP.
