What is gear pump, what are gear pump features?

Gear pump is the name given to rotary pumps; These are pumps that transport liquid using rotating gears. Gear pump pushes the liquid medium, creates vacuum pressure, completes its function with the use of two or more gears. Gear pumps have the ability to create very high pressure. It is one of the most common pump types in hydraulic fluid power applications. Its first discovery is based on a very old history. It was invented by Johanner Kepler in the 1600s. Gear pumps are a type of pump commonly used in chemical installations to pump high-viscosity liquids. Gear pumps pump a fixed amount of liquid per revolution. It provides a smooth, shock-free flow proportional to the rotational speed of the gears. They are suitable for pumping high viscosity liquids such as plastics, oils, paints, adhesives or soaps.

Gear pump working principle

Gear pumps are “positive displacement”; they pump a fixed amount of liquid per revolution. A rotating assembly of idle and drive gear moves to create suction and draw fluid at the pump inlet. As the liquid, directed to the discharge point between the walls of the case and the teeth of the gears, moves from the inlet to the outlet, the volume decreases, and this lack of volume causes pressure build-up. Flow in gear pumps determines the volume between the pump teeth, the rotational speed of the gears, represented in rpm, and the amount of slip. As the pump starts to wear, slip increases.
