HLR Hygienic Rotary Lobe Pumps
Operating principle
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.
Design and features
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.
