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

    2021-5-7 · Rotary lobe pumps are very popular in food applications because of their ability to carefully handle low shear fluids and solids, without damaging the product. Because the lobes do not touch, large particles are handled more easily than with other types of positive displacement pumps. It is also good for abrasive applications for the same reason.

    How does a lobe pump works? Lobe pumps work similarly to gear pumps except that the lobes do not come in contact with each other. In addition, lobe pumps have larger pumping chambers than gear pumps, which enable them to transfer slurries. They also tend to move slower in order to handle shear-sensitive materials.
