Rotary Lobe Pump SLR-A

Rotary Lobe Pump SLR-A

Application

The SLR-A pump is a positive displacement lobe rotor pump designed to transfer abrasive products. The pump offers high perfromance and reliability. It is characterised by a reduced size, detachable connections and rectangular casing inlet. The SLR-A pump is designed to pump olive mass. The main application is the transfer of the mass from the thermobeater to the decanter and the transfer of alperujo, solid olive-mill by-product, from the thermobeater to the decanter.

Operating principle

The SLR-A pump basically consists of two wing-lobe rotors which 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.
