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
