food product pump / rotary lobe / stainless steel / process

Rotor pump is called as rotary lube epump, sole pump, three-lobe pump, etc. When the simultaneously reverse-rotating 2 rotors (having 2-4 gears) revolve, they provide a suction force (vacuum) near the inlet, which takes-in the delivered material. The rotor housing is divided by the 2 rotors into various smaller parts revolving sequentially like a?b?c?d. When revolving goes to position a, medium is filled only in housing I, when it goes to b position, part of medium is enclosed by housing B, when it reaches position c, medium is enclosed by housing A, finally it arrives at position d and housing II, B and A get interlinked and its medium gets transported to its outlet. Material or medium is constantly transported as this process is repeated.
