CBGJ Series High-Pressure Hydraulic Gear Pump for Loaders

Product Overview: The CBGJ series is a high-pressure, floating bush-type gear pump specifically engineered for Wheel Loaders, road rollers, and cranes. As the “power core” of the loader’s hydraulic system, this series is widely utilized in the steering and working circuits of 3-ton, 5-ton, and heavy-duty loaders. Core models such as CBGJ2100 and CBGJ2080 are renowned for their exceptional rated pressure and impact resistance, ensuring peak volumetric efficiency under the most grueling site conditions. We provide a full range of configurations, including single pumps, tandem pumps (e.g., CBGj1040/1020), and triple pumps (e.g., CBGJ3100/1010C).

Key Technical Advantages:

• High Pressure & Volumetric Efficiency: Featuring a high-strength cast iron housing and floating side-plate compensation technology, it delivers a rated pressure of up to 25 MPa (250 Bar). Minimal internal leakage ensures rapid and powerful lifting and tilting operations.

• Versatile Multiple-Section Capability: Supports various displacement combinations. Triple pump models like the CBGj1040/1020/1020R can simultaneously supply oil to working, steering, and pilot circuits in a compact envelope, significantly saving installation space.

• Superior Contamination & Wear Resistance: The internal bushings are crafted from specialized alloys, reinforced to withstand the dust and variable loads typical of construction machinery, drastically extending service life under heavy-duty operations.

• 100% Interchangeability: Strictly compliant with national standards and OEM interface specifications. Models like the CBGj2063L and the XF priority valve series are direct “drop-in” replacements for original pumps in major brands like XCMG and Lonking.
