Lobe pumps are used in transfers of viscous products and fluids containing solid particles. Positive displacement gear pumps that do not disturb the structure of the products.
Lobe pumps consist of two lobe rotors rotating simultaneously in a casing without touching each other. As the rotors rotate, the space between the protrusions and the casing is filled with liquid, thus providing efficient pumping.
Lobe pumps are popular in a variety of areas with their hygiene, high efficiency, safety and on-site cleanability. It is widely used in food, chemistry, paper, beverage, pharmaceutical sector. In lobe pumps, the contact of the lobes is prevented by the timing drive gears. Since there is no contact between the lobes and they have a larger pumping reservoir than other pump types, they can transfer solid particles without damaging them. The pump is connected to the shaft of the lobe, the motor receives the motion of the timer with the drive gear and the other lobe is in the opposite direction. As the lobes move in opposite directions, the volume expands at the suction opening of the pump. Through the suction obtained, the liquid flows to the pump. The liquid that is transported between the lobes and the rotorcase moves toward the discharge mouth. The liquid does not pass through the lobes . The lobes penetrate inside the discharge port and push the liquid together with the pressure. In each turn of the pump shaft, liquid is transferred as much as the volume of the pump. Therefore, the pump’s capacity is directly proportional to its size and cycle.
