Description
Overview
The CBG2 gear pump is a high-performance medium and high-pressure hydraulic component, featuring a simple structure, reliable operation, excellent impact resistance, and convenient maintenance. As a core power element in hydraulic systems, it is optimized for higher displacement and stable pressure output compared to the CBG1 series. Adopting high-strength materials and refined structural design, this pump maintains a volumetric efficiency of no less than 92% even under long-term continuous operation, making it ideal for heavy-duty hydraulic systems requiring large flow and stable pressure.
Structural Features
-
Optimized Mounting Structure: Equipped with a square flange mounting design (Model code: B), which enhances installation stability and compatibility with various mechanical equipment. The integrated pump body and cover structure reduces assembly errors, ensuring consistent performance in harsh working environments.
-
Efficient Sealing System: Adopts a combination of mechanical seals and O-rings, effectively preventing high-pressure oil leakage. The sealing components are resistant to wear and oil aging, extending the pump’s service life and maintaining high volumetric efficiency during long-term operation.
-
Enhanced Load-Bearing Capacity: Supported by high-precision bearings, the pump exhibits strong radial load resistance, adapting to high-pressure (up to 20MPa) and high-speed (up to 2500r/min) working conditions. This design ensures stable operation even when subjected to sudden pressure fluctuations.

Model Coding Explanation
Taking “CBG2040 B F P R” as an example, the coding is interpreted as follows:
-
CBG: Product code, indicating the CBG series gear pump.
-
2: Series identifier, representing the CBG2 series.
-
040: Nominal displacement, 40 ml/r.
-
B: Installation form, square flange mounting.
-
F: Port form, flange connection.
-
P: Shaft extension form, flat key.
-
R: Rotation direction, dextrorotation (clockwise), which can be omitted if default; L stands for levorotation (counterclockwise).
Other common codes: H (shaft extension form, rectangular spline); L (port form, threaded mounting when used for port specification).
Applications
With its excellent performance in large displacement and stable pressure output, the CBG2 series gear pump is widely applied in hydraulic systems of engineering machinery, ship machinery, hoisting machinery, and mining machinery. It is particularly suitable for equipment requiring continuous high-power output, and can be customized into single pumps or double pumps according to actual working conditions, fully meeting the diverse power needs of different hydraulic devices.
