Rotary Gear Pumps (DIBX) are positive displacement pumps which depend on rotational motion rather than reciprocating motion during the pumps operational cycle. They can be designed to pump solids, liquids, gases or a mixture of the three. They are extensively used for loading-unloading and transferring of all types of petroleum products and viscous liquids. Rotary Gear Pumps (DIBX) move the fluid on a repetition inside an enclosed fixed volume with the use of interlocking gears and cogs. This transfers it mechanically with the use of cyclic pumping actions.
