CBGJ2063/2063/2040 Gear Pump for Loader | CBGJ2100/2080/2040 | High Pressure

LIC Hydraulic offers the CBGJ Series Triple Gear Pumps, the standard power solution for heavy-duty 5-ton wheel loaders. Featuring a high-tensile cast iron body and a modular three-stage design, models like CBGJ2063/2063/2040 provide independent hydraulic flow for work, steering, and auxiliary systems. Engineered for durability under peak pressures of $25\text{ MPa}$, these pumps are the preferred replacement parts for leading brands such as XCMG, SDLG, and LIUGONG.

Technical Features

• Heavy-Duty Cast Iron Housing: Provides superior structural rigidity and thermal stability compared to aluminum alternatives, preventing housing distortion under high-pressure cycles.

• Axial Clearance Compensation: Floating side plates automatically adjust internal clearances based on load, maintaining high volumetric efficiency throughout the pump’s lifespan.

• Reinforced Needle Bearings: Designed to handle significant radial loads and high vibration levels common in construction site environments.

• Modular Versatility: The triple-stage configuration allows for customized displacement combinations (e.g., 63/50/40) to match specific OEM requirements.

Expert Maintenance Tips

• Verify Rotation: CBGJ pumps are typically unidirectional. Ensure the “Left” or “Right” rotation matches your machine’s PTO to avoid damaging the shaft seals.

• Avoid “Dry Start”: Always prime the suction port with clean hydraulic oil before the first start to lubricate the needle bearings and gears.

• Inlet Filtration: Maintain a suction filter of $100\text{ mesh}$ and return-line filtration of $20\text{ }\mu m$. Contamination is the leading cause of “scoring” on the internal floating plates.
