CBGJ Series Double Gear Pump | CBGJ2050, CBGJ2080/1010 | XF11C0004 High-pressure Hydraulic Pump

CBGJ Series Heavy-duty Double High-pressure Hydraulic Gear Pumps

Product Overview: The CBGJ Series represents a premium line of heavy-duty cast iron gear pumps, serving as the reliable power core for large-scale construction machinery. This featured selection spans across the CBGJ0, CBGJ1, CBGJ2, and CBGJ3 frames, featuring flagship double pump configurations such as CBGJ2050 and CBGJ2080/1010. Specifically, the XF11C0004 model with an integrated priority valve ensures that the steering system receives a prioritized and stable oil flow regardless of the load conditions. Engineered with a robust axial pressure compensation structure, the CBGJ series delivers elite volumetric efficiency and extended service life even under continuous pressures of 25 MPa.

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 in mining and construction sites.

• Independent Dual-circuit Output: Models like the CBGJ2080/1010 allow a single drive shaft to power primary working hydraulics and auxiliary steering systems simultaneously, optimizing space and reducing energy loss.

• Integrated XF Priority Valve: The XF11C0004 model features an integrated priority valve that automatically regulates flow distribution for responsive steering and consistent operator effort.

• Precision Pressure Compensation: Equipped with automatic axial gap compensation side-plates to minimize internal leakage, maintaining efficiencies over 92% even as oil temperatures reach 80°C.

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