CBGJ Series Gear Pump | CBGJ2100/2080, CBGJ3125, CBGJ3160, CBGJ3166 | High Pressure Tandem Pump

CBGJ Series Heavy-Duty High-Pressure Hydraulic Gear Pumps

Product Overview: The CBGJ Series stands as the industry standard for high-performance, heavy-duty hydraulic pumps in construction machinery. This featured selection covers core single and tandem models, including CBGJ3125, 3160, 3166, and tandem configurations like CBGJ2100/2080 and the priority-valve integrated CBGj3100/2040-XF. Specifically engineered for loader lifting, steering, and excavator primary systems, these pumps utilize high-strength cast iron housings and floating bushing technology. Featuring superior axial pressure compensation, the CBGJ series delivers stable operation at pressures up to 25 MPa, making it the premier choice for hydraulic system overhaul and OEM replacement.

Key Technical Advantages:

• Heavy-Duty Cast Iron Build: Constructed with wear-resistant, high-strength cast iron bodies for superior thermal stability and impact resistance under frequent instantaneous pressure spikes.

• Versatile Tandem Integration: The CBGJ2 series supports multiple independent outputs from a single drive shaft, powering steering and working circuits simultaneously while optimizing plumbing.

• Superior Volumetric Efficiency: Equipped with automatic axial gap compensation to minimize internal leakage, maintaining efficiencies over 92% even as oil temperatures rise.

• Integrated XF Priority Valve: Specialized models like the CBGj3100/2040-XF feature integrated priority valves to ensure the steering system receives prioritized, stable flow under all conditions.

• Quiet & Smooth Performance: Precision-ground gear sets drastically reduce pressure ripples and vibrations throughout the entire hydraulic system.
