CBGJ2063/2050/2040 Triple Gear Pump | High Pressure Oil Pump for Loader Repair

The CBGJ Series Triple Gear Pump from LIC Hydraulic is a heavy-duty solution engineered for the global loader repair and maintenance market. Featuring integrated configurations like CBGJ2063/2050/2040 and CBGJ2063/2050/2032, this series provides a robust three-stage output to power steering, working hydraulics, and pilot control circuits simultaneously. We guarantee 100% mechanical interchangeability with major OEM specifications. Every triple pump undergoes 100% sequential efficiency testing and 25MPa high-pressure validation to ensure reliability in the harshest construction environments.

Technical Configuration Details

• Series Hierarchy: 2063 (Stage 1), 2050 (Stage 2), 2040/2032 (Stage 3).

• Pressure Rating: Nominal $20\text{ MPa}$ ($2900\text{ PSI}$); Peak $25\text{ MPa}$ ($3600\text{ PSI}$).

• Housing: High-tensile anti-wear cast iron for maximum structural rigidity.

• Efficiency: Advanced floating side plate design for axial pressure compensation.

• Shaft & Flange: Standardized spline shafts and 4-bolt flanges for direct drop-in replacement.

Key Technical Advantages

• Integrated Multi-Circuit Power: The triple-stage design minimizes the footprint within the engine compartment while providing dedicated flow for different hydraulic functions, reducing complex plumbing.

• Durability in Extreme Conditions: Precision-ground alloy steel gears and oversized needle bearings are designed to handle the high-frequency pressure spikes common during heavy-duty scooping and lifting operations.

• High Volumetric Efficiency: The internal pressure-balanced structure maintains over $92\%$ efficiency throughout the pump’s service life, preventing power loss as the machine ages.

• Precision Interchangeability: Manufactured to strict tolerances to ensure a perfect fit for repair projects on major wheel loader brands, reducing downtime during overhauls.

Application Areas

• Wheel Loader Overhaul: Primary replacement pump for 5-ton to 8-ton class construction loaders.

• Mining Equipment: Reliable hydraulic supply for underground loaders and material handlers.

• Mobile Hydraulics Repair: Used by service centers to restore hydraulic speed and breakout force in aging fleets.

Expert Maintenance Tips

• Initial Priming: Always prime each of the three pump sections through the inlet or outlet ports before the first startup. A “dry start” on even one section can cause catastrophic internal scoring.

• Shaft Alignment: Ensure that the drive shaft alignment is within specified limits. Excessive radial or axial loads can lead to premature shaft seal failure and internal bearing wear on the primary section.

• Oil Cleanliness: Maintain fluid cleanliness to ISO 4406 19/17/14. Contamination from one circuit can easily affect the entire triple pump assembly via the common suction or reservoir.
