There is a Gear Pump offered by us that is a type of positive displacement (PD) pump . It moves a fluid by repeatedly enclosing a fixed volume using interlocking cogs or gears, transferring it mechanically using a cyclic pumping action. It delivers a smooth pulse-free flow proportional to the rotational speed of its gears. The pumps are rotary pumps in which two or more gears mesh to provide the pumping action. The Gear Pump is made for use in the various applications.
