VOGELSANG rotor pump and Gear pump Both are common positive displacement pumps, but their operating principles and structures are different. The following are their primary differences:

Operating principle: the cam rotor pump has positive displacement through the rotation of the rotor in the meter, so as to realize the suction and discharge of liquid; The gear pump absorbs and discharges liquid through the space between two meshing gears.

Structure: cam rotor pump is mainly composed of inner rotor, outer rotor, housing and end cover; The gear pump is composed of two gears, a housing and an end cover.

Working noise: because the rotor clearance in the cam rotor pump is very small, the liquid movement in the pump body is very stable, so the working noise is small; The gear pump has relatively large working noise because of the meshing of gears.

Application: Cam rotor pump is suitable for transporting viscous liquids, such as grease, asphalt, paint, etc; The gear pump is suitable for transporting low viscosity liquid, such as gasoline, lubricating oil, etc.

In conclusion, although both cam rotor pump and gear pump belong to positive displacement pump, their operating principles and structures are very different, and they are suitable for different occasions.
