Internal Gear Pump
Principle
The meshing gear pump adopts the principle of internal meshing of gears. The pitch circles of the inner and outer gears are close to one side, and the other side is separated by a “crescent plate” on the pump cover. The driving inner gear on the main shaft drives the outer gears to rotate in the same direction. At the inlet, the gears are separated from each other to form a negative pressure to suck in the liquid, and the gears are continuously embedded and meshed at the outlet to squeeze the liquid out.
Because of this unique structure, it is especially suitable for conveying medium with high viscosity, the viscosity range is: 0.2-1000000cp.
