CBJ High Pressure Gear Pump – Built Tough by Changjiang Hydraulics

When your hydraulic system demands non-stop power, you need a gear pump that never lets you down. The CBJ Series High Pressure Gear Pump, manufactured by Changjiang Hydraulics, delivers exactly that—reliability, efficiency, and raw power.

Proven High-Pressure Performance

Designed for construction machinery, agricultural equipment, and industrial vehicles, the CBJ series operates smoothly under extreme loads. With rated pressures up to 25–31.5 MPa, this pump maintains stable flow even in the toughest conditions. Its high-strength cast iron housing resists deformation, while hardened alloy steel gears provide superior wear resistance.

Precision Manufacturing

At Changjiang Hydraulics, every CBJ pump is produced using advanced CNC machining and strict quality control. The gears are precisely ground to minimize internal leakage, achieving volumetric efficiency above 94%. This means more output, less energy waste, and cooler operation.

Low Noise, Long Life

Thanks to optimized tooth profiles and dynamic balancing, the CBJ runs quietly and smoothly. Reduced pulsation protects your entire hydraulic system, extending component life. Whether you need a single pump or a duplex configuration, Changjiang Hydraulics offers flexible solutions.
