  • How Do Rotary Lobe Pumps Work? | verderliquids.com

    2011-3-3 · Rotary pumps use a variety of means to generate flow. A pair of gears with many teeth (external to the gear and called an external gear pump) in gear pumps or a few lobes in lobe pumps is demonstrated in Fig. 23.2.Internal gear pumps use a gear within a gear design; internal means the teeth of one gear are on the inside, projecting inward. Gear pumps are useful for …

    2020-8-7 · Lobe pumps. Lobe pumps use two rotors containing two or three lobes which direct the flow of the fluid being pumped. These rotors are located in their own shaft, and the lobes mesh together as they rotate inside the pump casing. As the rotors turn in the casing, a vacuum is created which draws the fluid into the pump.
