Applications

Rotary lobe pump is a lobe rotor positive displacement pump of a sanitary design suitable for use in the dairies, food-processing, beverage, pharmaceutical and fine chemicals industries.
This pump is perfect for managing all kinds of fluid, of either low or high viscosity, in the food-processing, dairies, and cosmetics industries, as well as for filtering and bottling applications. Fluids containing fragile solids such as junket can be pumped without damage thanks to the specially designed lobes.

Operating principles 

Rotary Lobe pumps basically consist of two lobe rotors which rotate synchronously inside a casing without touching each other.The two rotors divide the rotor chamber into to several smaller rooms and move in order he medium is delivered to the outlet. With this circulation, the medium (material) is delivered through the pump continuously.
