HY Series High-Pressure Axial Piston Variable Pumps

Product Overview: The HY series (evolved from the classic CY14-1B technology) serves as the powerhouse for high-pressure industrial hydraulic systems. As an axial piston variable displacement pump, this series spans a comprehensive displacement matrix from 25cc to 250cc. Featured models include the HY40Y-RP, HY63Y-RP, and HY160Y-RP. Engineered for sustained high-pressure operation, the HY series utilizes advanced valve plate balancing and reinforced piston groups. It is widely utilized in metal forming presses, forging equipment, mining machinery, and large-scale industrial Hydraulic Power Units (HPU), ensuring stable performance up to 31.5 MPa.

Key Technical Advantages:

• Versatile Control Modes: Available with RP (Manual Control), L (Constant Power), and P (Pressure Compensation), allowing precise displacement modulation to minimize system heat and energy consumption.

• Heavy-Duty High-Pressure Ratings: Built with high-strength castings to support a continuous operating pressure of 31.5 MPa (4500 PSI), capable of enduring rigorous industrial duty cycles.

• Extended Life Rotating Groups: Reinforced pistons and slipper components utilize wear-resistant materials to maintain peak volumetric efficiency even with varying hydraulic fluid qualities.

• Service-Friendly Design: Compact structure with high component standardization; internal parts (e.g., rotating groups, valve plates) are easily replaceable, drastically reducing maintenance downtime.

• High Power Density: Delivers large flow outputs within a minimal footprint, making it the ideal choice for heavy machinery power upgrades and OEM applications.
