CBGJ & CBY Series High Pressure Gear Pump | CBGJ 3100/1032, 1016, 1010 | CBY2025-1TR, 2040

CBGJ & CBY Series Heavy-Duty High-Pressure Hydraulic Gear Pumps

Product Overview: The CBGJ and CBY Series represent the pinnacle of hydraulic pump engineering for large-scale construction machinery and heavy-duty equipment. Built with high-tensile cast iron bodies, these pumps offer superior resistance to deformation and long-term wear. This featured range includes core models: CBGJ 3100/1032, 3100/1016, and 3100/1010 (frequently utilized in tandem or multi-stage configurations), alongside the CBY2025-1TR and CBY2040-1TR specifications. Equipped with high-performance floating bushings and specialized side plates, these pumps maintain a volumetric efficiency above 92%, even under continuous high pressure and transient shock loads.

Key Technical Advantages:

• Heavy-Duty Cast Iron Construction: The high-quality cast iron housing effectively absorbs internal hydraulic vibrations, preventing body cracking or deformation during sustained high-pressure operation.

• Integrated Tandem Design: Models like the CBGJ 3100 series support multiple displacements (e.g., 100ml + 32ml) on a single drive shaft, independently powering steering and primary work circuits.

• Superior Impact Resilience: Rated for continuous pressures up to 20-25 MPa (200-250 Bar), specifically optimized for the frequent direction changes and high-frequency shocks found in loaders and excavators.

• Automated Axial Gap Compensation: Floating bushing technology real-time adjusts clearances based on load pressure, ensuring stable flow output and peak power performance throughout the pump’s lifecycle.

• Target Applications: Wheel loaders (XCMG/Liugong style), heavy-duty excavators, roller steering systems, mining machinery, and specialized industrial vehicles.
