Operations
The operation principle of gear pumps is based on positive displacement. Two meshing gears rotate inside the pump housing, creating chambers between the teeth. As the gears rotate, liquid is trapped in these chambers and carried around the outer circumference from the pump’s inlet to the outlet. The tight fit between the gears and housing prevents backflow. As the gears mesh again at the discharge side, the fluid is forced out, delivering a consistent, smooth flow. This makes gear pumps ideal for handling viscous fluids and high-pressure applications.
Types of Gear Pumps
There are two main types of gear pumps: internal and external. Both types function through a driving gear that moves an idler gear, using the meshing and unmeshing of the gears to generate fluid flow. The key difference lies in the arrangement of the gears and where the fluid is trapped. In internal gear pumps, the gears are positioned one inside the other, while in external gear pumps, the gears are side by side, with the fluid trapped between the gear teeth and the pump housing.
