Operating principle
The SLR-A pump basically consists of two wing-lobe rotors that rotate inside the casing without touching each other. As the rotors rotate, the space between the lobes and the casing is successively filled with the product which is driven to the discharge nozzle displacing a fixed amount of product. The pumped product forms a continuous stream due to the adjusted tolerances between the lobes and the pump casing, thus, ensuring an efficient pumping.
