There are various types of gears in gear pumps

There are various types of gears in gear pumps, including straight teeth, involute helical teeth, circular arc teeth, octagonal teeth, axe teeth, etc. According to different gears, it can be divided into KCB gear pump, 2CY gear pump, circular arc gear pump, cam gear pump, high viscosity rotor pump, etc. The involute helical gear pump produces significant noise during operation due to the formation of trapped liquid at the bottom of the gear teeth; Spur gears also belong to involute gears. The advantage of spur gear pumps is that they have higher conveying viscosity and pressure than involute helical gear pumps; The circular arc gear type gear pump has a continuous contact point between two meshing tooth profiles, which does not cause oil entrapment and solves the problems of vibration, noise, and increased bearing load caused by oil entrapment in involute gear pumps. Circular arc gear pump is a gear pump with high efficiency, low noise, and long service life in the gear pump series.
