Lobes Type SLA rotary lobe pumps basically consist of two lobe rotors which rotate synchronously inside a casing without touching each other. 4s the rotors rotate, the spaces batween the lobes and the casing are filled with the product, which is transported to the discharge nozzle with a fixed amount of displacement. The pumped fluid forms 4 continuous straam thanks to the tolerances between the lobes and the pump casing, thus ensuring an efficient pumping.
