What is a gear pump

Gear pump is a kind of positive displacement pump, which consists of two gears, the pump body and the front and the back cover to form two enclosed spaces. When the gear rotates, the volume of the space on the side of the gear to be disengaged increases from small to large to form a vacuum, The volume of the space on the engagement side is reduced from large to large, and the liquid is squeezed into the pipe. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the outlet of the gear pump depends entirely on the resistance of the pump.
