CBGJ3 Series High Pressure Gear Pump | CBGJ3100 CBGJ3160 CBGJ3200 | Loader Hydraulic Pump

LIC Hydraulic provides the CBGJ3 Series, a powerhouse in high-pressure hydraulic technology specifically optimized for the construction and mining industries. As a staple for heavy-duty loaders, models ranging from CBGJ3100 to CBGJ3200 are engineered to withstand the most punishing environments. With a nominal pressure of $25\text{ MPa}$ ($3625\text{ PSI}$) and peak capabilities up to $31.5\text{ MPa}$, these pumps ensure that your machinery has the breakout force and lifting speed required for maximum productivity.

Key Technical Advantages

• Heavy-Duty Cast Iron Construction: The robust cast iron housing provides superior structural integrity compared to aluminum alternatives, resisting body expansion and fatigue under constant high-pressure cycling.

• Pressure-Balanced Efficiency: Utilizing floating bush technology, the CBGJ3 series maintains optimal clearance between gear faces and side plates, ensuring high volumetric efficiency even as the pump ages.

• High Load Capacity: Equipped with premium DU bushings and hardened gear shafts, these pumps handle the radial loads common in engine-driven loader applications without premature failure.

• Versatile Mounting: Available in standard SAE or specialized splined shafts to fit major global loader brands such as SDLG, Lonking, and Liugong.

Application Areas

• Wheel Loaders: Main hydraulic power for lift and tilt cylinders.

• Earthmoving Equipment: Steering and auxiliary hydraulic circuits for bulldozers and graders.

• Industrial Material Handling: Powering heavy-duty forklifts and reach stackers.

Expert Maintenance Tips

• System Priming: Before restarting a loader after a pump change, fill the pump housing with fresh oil. Dry-starting a large displacement pump like the CBGJ3200 can cause immediate damage to the internal wear plates.

• Check Inlet Filters: Ensure the suction strainer is clean. Large displacement pumps are highly sensitive to “starvation,” which can lead to rapid internal erosion.

• Monitor Pressure Relief Valves: Ensure the system’s main relief valve is set correctly. Frequent operation at the pump’s peak pressure ($31.5\text{ MPa}$) without proper relief will significantly shorten the gear life.
