Powering Precision and Reliability: The Changjiang Hydraulic CBG-Fa2080/2080-B2BR Dual Gear Pump in Modern Engineering

In today’s advanced engineering landscape, hydraulic systems serve as the lifeblood of heavy machinery—enabling precise control, immense power transmission, and consistent performance across diverse applications. At the heart of these systems lies the hydraulic gear pump, a critical component responsible for converting mechanical energy into hydraulic flow. Among the leading solutions in this domain is the Changjiang Hydraulic CBG-Fa2080/2080-B2BR dual gear pump, a high-performance, tandem-configured unit engineered for demanding industrial and mobile hydraulic applications. Renowned for its robust construction, efficiency, and versatility, this pump has become a preferred choice for manufacturers and operators worldwide.

Dual-Stage Design for Enhanced System Integration

The standout feature of the CBG-Fa2080/2080-B2BR is its tandem (dual) gear pump architecture, which integrates two identical displacement gear pumps—each with a displacement of 20.8 cc/rev—into a single, compact housing. This design allows the pump to simultaneously supply hydraulic fluid to two independent circuits, such as a primary working system (e.g., boom or bucket actuation) and an auxiliary function (e.g., cooling fan or steering). By eliminating the need for separate pumps, the CBG-Fa2080/2080-B2BR reduces system complexity, saves installation space, lowers weight, and minimizes potential leak points—all while maintaining synchronized performance.

High Efficiency and Pressure Capability

Engineered for modern high-load operations, the CBG-Fa2080/2080-B2BR supports a maximum continuous operating pressure of up to 21 MPa (3,045 psi), with peak pressures tolerated for short durations. Its precision-machined gears, hardened shafts, and optimized internal clearances ensure minimal internal leakage and high volumetric efficiency—often exceeding 90% under standard operating conditions. This translates into consistent flow delivery, reduced energy waste, and lower fuel consumption in engine-driven applications, making it ideal for eco-conscious engineering projects.

Robust Construction for Harsh Environments

Built to endure the rigors of construction sites, mining operations, and agricultural fields, the pump features a high-strength cast iron housing that resists deformation under thermal and mechanical stress. The gears are crafted from alloy steel and undergo carburizing and grinding processes to enhance surface hardness and wear resistance. Additionally, the B2BR suffix denotes specific porting configurations and shaft options (typically a splined or keyed shaft compliant with SAE standards), ensuring compatibility with a wide range of power take-offs (PTOs) and drive systems.

Sealing is another area of excellence: premium-grade NBR or FKM seals prevent oil leakage and protect against contamination ingress, even in dusty or humid environments. This reliability significantly extends maintenance intervals and reduces total cost of ownership.

Broad Application Spectrum

The versatility of the CBG-Fa2080/2080-B2BR makes it suitable for a wide array of engineering machinery:

• Excavators and Loaders: Powers both main hydraulic functions and pilot or cooling circuits.

• Agricultural Tractors and Harvesters: Drives implements and steering systems simultaneously.

• Road Construction Equipment: Used in asphalt pavers, cold planers, and rollers requiring dual hydraulic outputs.

• Material Handling Systems: Supports lift mechanisms and stabilizer legs in telehandlers and forklifts.

Its standardized mounting flanges (SAE A or B) and port orientations allow seamless integration into existing hydraulic layouts, facilitating both OEM installations and aftermarket replacements.

Commitment to Quality and Global Standards

Changjiang Hydraulic, a well-established Chinese manufacturer with decades of experience in fluid power technology, produces the CBG-Fa2080/2080-B2BR under stringent quality control protocols aligned with ISO 9001 standards. Each unit undergoes rigorous performance testing—including flow rate verification, pressure endurance checks, and noise evaluation—before shipment, ensuring consistent reliability in the field.
