Inoxpa HLR Hygienic Rotary Lobe Pump

Inoxpa HLR hygienic pump is a positive displacement rotary lobe pump that benefits from sanitary and cost-efficient design. Suitable for use in the brewery, dairy, food-processing, beverage, cosmetics, pharmaceutical and fine chemicals industries, this sanitary pump is designed in compliance with the EHEDG specifications for plants and processes that comply with the strictest hygienic requirements. HLR sanitary pump has a versatile type of pump design, able to transfer a large range of high and low viscosity fluids (from 1 to 1.000.000 cP) efficiently. In addition, the Inoxpa pump can safely pump fluids containing fragile solids without damage and shear sensitive media thanks to the specially designed lobes and the lower working speed.

Inoxpa pumps are meticulously manufactured to ensure reliable, long-lasting operation as well as provide easy cleaning and maintenance. Made of stainless steel to ensure compliance with hygienic requirements and contamination-free fluid transfer, this HLR stainless steel sanitary pump provides fast and optimal performance. This hygienic pump comes with an internal single mechanical seal that has a hygienic design. As standard, the stationary part is in carbon, the rotary part is in silicon carbide, and the gaskets are in EPDM. However, when required, the HLR hygienic pump can be supplied with other materials compatible with the pumped fluid.

Operating Principle

The HLR sanitary pump 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.
