Hygienic rotary lobe pumps for food and pharma duties

Inoxpa’s SLR Rotary Lobe Pump is suitable for pumping applications which involve liquids containing solid particles such as chocolates and fats or those that are highly viscous, including syrups, honeys and gels. The SLR pump is a positive displacement sanitary construction rotary lobe pump for use in the dairy, food processing, beverage, cosmetic, pharmaceutical and fine chemical industries.

The pump incorporates two lobe rotors which rotate synchronously inside a casing without contact. As the rotors turn, the spaces between the lobes and the casing are filled with the product, and a fixed volume is displaced with each rotation. The pump generates a continuous smooth flow thanks to the tolerances between the lobes and the pump casing, enabling efficient, low shear pumping.

SLR pumps feature an RA surface finish of less than or equal to 0.8µm, a bright polished external finish and gaskets/seals to FDA standards to ensure no contamination to food products or other sensitive ingredients.

The pump is also reversible allowing for unload/offload duties to be performed with the same pump. Units are supplied with hygienic DIN 11851 connections, although other options including RJT, SMS and tri-clamp are available to provide flexibility for specific onsite requirements.

Options to suit specific pumping applications are also available including heated jacket to ensure product temperature is maintained and an ATEX rated option allowing flammable liquids to be handled safely.
