CBGJ2/1 Series Double Gear Pump | CBGJ2080/1025 | CBGJ2125/1045

LIC Hydraulic presents the CBGJ2/1 Series, a robust range of tandem high-pressure gear pumps designed for the most demanding mobile machinery. With its high-tensile cast iron housing and specialized floating side plates, models like the CBGJ2080/1025 deliver consistent flow and power under continuous peak loads. This tandem configuration allows for the synchronization of two independent hydraulic circuits, making it the preferred choice for heavy-duty loaders and road rollers worldwide.

Key Technical Features

• Cast Iron Durability: The heavy-duty housing eliminates body flexing under high pressure, maintaining precise internal clearances and extending seal life.

• High Volumetric Efficiency: Advanced axial pressure balancing ensures over $90\%$ efficiency even during extreme temperature fluctuations.

• Tandem Versatility: Combines a high-flow front section with a medium-flow rear section, perfect for steering and auxiliary functions driven by a single engine PTO.

• Heavy-Duty Internal Components: Precision-ground gears and high-load bearings provide whisper-quiet operation and reduced vibration.

Expert Maintenance Tips

• Check Rotation: CBGJ pumps are rotation-specific. Operating a Clockwise (Right) pump in Counter-Clockwise (Left) rotation will cause catastrophic internal failure.

• Inlet Vacuum: Ensure the suction line is large enough to prevent cavitation, especially in cold start conditions. Voids in the oil will quickly pit the cast iron gears.

• Filtration Standard: To protect the precision-lapped side plates, maintain hydraulic oil cleanliness at ISO 4406 20/18/15 or better.
