Rotary Lobe Pump – Sanitary

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

The Inoxpa SLR rotary lobe pump basically consists 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 the product, 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.
