CBY2 Hydraulic Pump Gear

CBY2 Gear Pump  Overview

The CBY2 is a high-performance, fixed-displacement external gear pump engineered for demanding industrial and mobile hydraulic systems that require reliable high-pressure output and long service life. Built with robust construction and optimized hydraulic design, the CBY2 is specifically designed to deliver consistent power in compact installations, making it ideal for use in construction machinery, agricultural equipment, and industrial machinery where performance and durability are critical.

Features and Benefits

• Rugged High-Strength Construction

  The CBY2 is built with high-grade cast iron bodies and covers, offering superior structural rigidity compared to lighter alternatives. This heavy-duty construction minimizes deflection under high-pressure loads, reducing mechanical fatigue and ensuring stable, leak-free performance in harsh operating environments.

• High-Efficiency Gear and Bearing Design

  Featuring precision-machined alloy steel gears and pressure-balanced support elements, the CBY2 maintains high volumetric efficiency even at continuous high pressures. The design effectively reduces internal leakage and friction, supporting long-term operation with minimal wear and consistent output flow.

• Advanced Axial Compensation Technology

  Equipped with pressure-balanced wear plates, the CBY2 automatically adjusts internal clearances between the gear faces and housing. This minimizes fluid bypass and mechanical friction, delivering exceptional mechanical efficiency and reliable power delivery across a wide range of operating temperatures and load conditions.

• Superior High-Pressure Capability

  Despite its compact footprint, the CBY2 is engineered to handle continuous operating pressures of up to  25 MPa (250 bar). Its precision components and robust design allow it to power high-force actuators and complex hydraulic circuits with smooth, dependable flow in demanding applications.

• Modular Versatility and Installation Flexibility

  The CBY2 series offers a versatile range of displacements (typically from  4 to 100 cc/rev) and supports standard SAE and common industry mounting configurations. With multiple porting options and a compact form factor, it provides excellent installation flexibility for space-constrained mobile equipment and industrial systems.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
