Internal gear pump is a hydraulic pump which adopts the principle of internal gear meshing. Its main structure and features include:

Structure: The internal gear pump is mainly composed of two meshing gears, one of which is a rotor with an internal gear and a rotor with an external gear, and the two rotors mesh through a vertical shaft. The pump body is provided with a plurality of fixed sealed working chamber, which helps to ensure the suction and discharge of liquid.
Working principle: The active inner gear on the main shaft drives the outer gear to rotate in the same direction, and the gear is separated from each other at the inlet to form negative pressure and inhale the liquid, and the gear is constantly embedded in the mesh at the outlet to squeeze the liquid. The inner and outer gear pitch circles are close to one side, and the other side is separated by a “crescent plate” on the pump cover.
Characteristics: Due to this unique structure, the internal gear pump is especially suitable for conveying medium with high viscosity, viscosity range is 0.2-1000000cp. In addition, the internal gear pump also has the advantages of reverse transmission, the pump body can be turned, the import and export position is at a right Angle, the transmission is smooth, the efficiency is high, the noise is low and the service life is long.

Internal gear pump is widely used in industry, agriculture, aerospace and other fields, such as petroleum, chemical, paint, dye, food, grease, medicine and other industries in the Newtonian liquid or non-Newtonian liquid delivery. Its materials are cast iron, cast steel, stainless steel, etc., can be selected according to the specific needs of the appropriate material.
