Gear ring hydraulic pumps

The gear ring pump is primarily used as a pressure lubrication system for machines and combustion engines. They are also used in hydraulic power steering systems.

This pump is often assembled with a high-pressure pump, e.g. radial piston pump. The rotors of the gear ring pump can be directly built into the high-pressure pump’s housing, making it possible to build very compact units. Such small double pumps are often used for rapid traverse on large presses and tensioning equipment.

The rotor has one tooth less than the inner stator. Planetary movement of the rotor results in compressing and decompressing of the displacement chambers within the housing.
