YCY14-1B Series Pump | 10YCY, 25YCY, 40YCY, 63YCY, 160YCY | High Pressure Variable Piston Pump

YCY14-1B Series High-Pressure Pressure-Compensated Axial Piston Pumps

Product Overview: The YCY14-1B series is an industrial-grade high-pressure axial piston variable pump featuring a pressure-compensation regulator, serving as the core power unit for open-circuit hydraulic systems. Renowned for its “Constant Pressure Variable” performance, the series spans a full displacement spectrum from the compact 10ml/r to the high-capacity 160ml/r. Featured models include the 10YCY14-1B, 25YCY14-1B, 40YCY14-1B, 63YCY14-1B, and the heavy-duty 160YCY14-1B. When system pressure reaches the preset value, the pump automatically reduces displacement to maintain constant pressure, drastically lowering energy consumption and heat generation. It is the premier choice for metal-cutting tools, forging machinery, plastic machinery, and large-scale industrial Hydraulic Power Units (HPU).

Key Technical Advantages:

• Precise Pressure Compensation: Integrated regulator supports flexible pressure setting between 8 – 31.5 MPa, ensuring minimal power consumption during the pressure-holding phase.

• Heavy-Duty High-Pressure Ratings: Rated at 31.5 MPa (4500 PSI) continuous operation, featuring reinforced piston groups and balanced valve plates for extended life under high-pressure pulsations.

• Significant Energy Savings: Automatically modulates flow output to match load requirements, eliminating relief losses and stabilizing the thermal balance of the entire hydraulic system.

• Rugged & Durable Construction: High-strength ductile iron housings provide excellent shock resistance, capable of handling 24/7 continuous industrial duty cycles.

• Standardized Interchangeability: Strictly adheres to the classic 14-1B technical standards, with unified flanges, shafts, and port specifications for seamless replacement in domestic and international equipment.
