Applications
This pump is deal for the transfer of viscous as well as low-wiscous media in the food processing, cosmetics and pharmaceutical Industries.

Principles
1. As the lobes rotates, the space on the suciton side increasese as one lobe is distanced from another, thus creating a partial vacuum which draws the fluid in to the pump chamber.
2. As they are rotated by the shafts,each lobe is consecutively filled and the fluid is displaced to the delivery side.The small gaps between the robes and between the lobes and the walls of the pump body ensure that the spaces are duly filled.
3. The pump housing is ompletely filled and the fluid escapes through the teeth of the lobes and is forced against the walls of the spaces. Which contributes to the pump aciton
