SLR LOBE ROTOR PUMP

Applications

The SLR 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

The SLR pumps basically consist of two lobe rotors which rotate synchronously inside a casing without touching each other.
As the rotors rotate, the spaces between the lobes and the casing are successively filled with fluid, which is transported to the discharge nozzle with a fixed amount of displacement. The pumped fluid forms a continuous stream thanks to the tolerances between the lobes and the pump casing, thus ensuring an efficient pumping.
