CBG & CBGJ Series Hydraulic Gear Pump | CBGJ3125, CBG2080, JHP2063 | High Pressure Tandem Pump

CBG, CBGJ & JHP Series Heavy-Duty High-Pressure Hydraulic Gear Pumps

Product Overview: The CBG, CBGJ, and JHP Series serve as the vital power heart for large-scale construction machinery hydraulic systems. This selection covers a comprehensive range of models optimized for heavy-duty cycles: high-pressure single pumps including CBG2063, 2080, 2100, 2040, 2050, JHP2063, and CBGj2080, as well as high-performance tandem configurations like CBGJ3125/3100 and CBGJ3160/3140. Engineered with high-strength cast iron housings and advanced axial pressure compensation, these pumps are specifically designed to meet the rigorous demands of loaders, bulldozers, and cranes for high pressure (up to 25 MPa) and large flow rates.

Key Technical Advantages:

• 100% Plug-and-Play Replacement: Strictly adheres to original construction machinery OEM specifications, ensuring that mounting flanges (SAE standard), drive shafts (splined or keyed), and port positions are 100% identical to mainstream brands.

• Rugged Cast Iron Construction: The high-tensile iron housing provides superior fatigue resistance and thermal stability, effectively handling the frequent instantaneous pressure spikes typical of heavy-duty cycles.

• Efficient Tandem Integration: Tandem configurations like the CBGJ3125/3100 allow a single power source to simultaneously supply precise flow to both working and steering circuits, streamlining system layouts.

• Superior Volumetric Efficiency: Featuring automatic axial gap-compensated wear plates to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life and reducing system heat generation.

• Smooth & Low Pulsation: Precision-ground gear sets drastically reduce pressure ripples under high-pressure cycles, protecting downstream control valves and enhancing operational precision.
