2 pe gear pumps, also known as external gear pumps, operate on the principle of intermeshing gears to create fluid flow. Each pump typically consists of two gears—an outer gear and an inner gear—that rotate together in a tightly meshed configuration within a pump casing.
Firstly, in a 2PE gear pump, fluid enters the inlet port where it is trapped between the teeth of the outer gear and the casing. As the gears rotate, the fluid is carried around the outer diameter of the gears to the outlet port. This movement creates a low-pressure area at the inlet side, allowing more fluid to enter and ensuring a continuous flow.
Secondly, inside the pump, the meshing of the gears forces the fluid outwards along the teeth of the gears. The fluid is then squeezed into the outlet port as the gears rotate and the meshing point moves towards the outlet. This squeezing action increases the pressure of the fluid, enabling the pump to generate the necessary hydraulic power.
Two-pe gear pumps are valued for their simplicity, reliability, and ability to handle a wide range of viscosities and pressures. They are commonly used in hydraulic systems, lubrication systems, and other applications where efficient fluid transfer and pumping are required.
