Applications
Applications
Construction & Road Machinery: A primary choice for excavators, loaders, graders, and road rollers, where the CBY2’s robust design delivers stable hydraulic power for lifting, digging, and steering functions in demanding worksite environments.
Agricultural Equipment: Optimized for tractors, harvesters, seeders, and fertilizer spreaders, handling variable load shocks, fluid contamination, and continuous-duty cycles common in outdoor field operations.
Material Handling & Logistics: Widely used in forklifts, truck tail-lifts, hydraulic ramp systems, and dock equipment, providing durable, space-efficient power for lifting and loading operations.
Industrial Hydraulic Power Units: Ideal for machine tools, presses, and conveyor systems, offering consistent pressure output and high volumetric efficiency for continuous production cycles.
Specialized Mobile Equipment: Frequently employed in drilling rigs, utility vehicles, and aerial work platforms, where its high-pressure capability and compact form factor meet the strict space and performance requirements of mobile chassis installations.
Factory&FAQ

CBY2 pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Pressure-Balanced Wear Plate Design: Unlike conventional pumps, the CBY2 uses pressure-compensated wear plates that automatically adjust clearances, minimizing internal leakage and maintaining high volumetric efficiency over time.
High-Pressure Rated Construction: With robust cast iron housings and precision-machined alloy steel gears, it maintains stable performance under continuous high pressure, reducing fatigue and extending service life.
Broad Modular Versatility: The series offers a wide range of displacements, mounting flanges, and port configurations, making it adaptable to a vast number of standard and custom applications.
Continuous Rated Pressure: Up to 20 MPa (200 bar / 2,900 PSI).
Intermittent/Peak Pressure: Up to 25 MPa (250 bar / 3,625 PSI).
This robust pressure rating makes the CBY2 ideal for driving high-force actuators and demanding hydraulic circuits in construction and agricultural machinery.

To ensure a successful swap, verify the Mounting Flange (SAE standard), Shaft Type (keyed or spline), and Displacement (cc/rev) to match your existing system.
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) and anti-foam additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 20 to 30 cSt, though it can handle cold starts up to 430 cSt.
Filtration: Cleanliness is vital to prevent wear. A minimum filtration level of ISO 4406 19/16/13 is recommended to protect components from abrasive contamination.
Rated Speed: 2,000 rpm (standard).
Maximum Continuous Speed: Up to 3,000 rpm (depending on displacement).
Operating within the recommended speed range ensures optimal lubrication, noise performance, and component longevity.

CBY2 pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
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.
