Lobe Pump


Lobe Pumps are driven by Timing Gears. Thanks to the said Timing Gears, it enables the Body, which is located on the parallel shafts and made of completely stainless steel, to rotate without touching each other or between the body and the lobe. The drive of the pump is provided by transferring the rotational movement received from the reducer to the timing gear rotated from the rotating timing gear in the opposite direction.

Due to the hygienic material and design of Lobe Pumps, it can provide reliability, transfer the liquid without disturbing its structure, and obtain pressure up to 12 Bar depending on the viscosity of the liquid.

The colored part on the side shows the entrance of the liquid into the suction nozzle area of the pump body, into the lobe cavities area thanks to the rotating and turned external gears. Black arrows show the pump rotation and the progress of the fluid.


As can be seen, fluid transport occurs between the lobes and the body that contains the lobes. Fluid does not pass between lobes.


We can see how the spaces between the lobe and the lobe body form a closed pocket for the fluid. This image shows the situation when the pump is completely filled and the liquid flows through the discharge port. Finally, with the power of the lobes, the fluid is delivered under pressure to the outlet.
