Beverage pump HLR series

with electric motorself-primingrotary lobe

The HLR pump is a hygienic 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. This hygienic 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. 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
