HLR Hygienic Rotary Lobe Pump

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.

HLR Hygienic Rotary Lobe Pump

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.

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.
