CY14-1B Series Pump | 5MCY, 25YCY, 40MCY, 80YCY | 31.5 MPa High Pressure Piston Pump

CY14-1B Series High-Pressure Axial Variable Piston Pump (31.5 MPa)

Product Overview: The CY14-1B series is a high-performance cornerstone of industrial hydraulic systems, featuring a rated pressure of 31.5 MPa. This series covers a comprehensive displacement range from the compact 5MCY to the heavy-duty 160MCY. Renowned for its unique “center return” design and high mechanical efficiency, the CY14-1B pump offers multiple regulation modes—including MCY (Fixed), YCY (Constant Pressure), SCY (Manual Variable), and PCY (Constant Power)—to meet diverse operational requirements. Its rugged cast-iron housing and reinforced rotating group ensure stable performance under 24/7 continuous heavy-duty cycles.

Key Technical Advantages:

• Ultra-High Pressure Capability: Rated at 31.5 MPa (315 Bar / 4568 PSI), it is ideal for heavy-duty hydraulic equipment requiring massive force or torque.

• Versatile Variable Control Modes:

  • MCY Series: Fixed displacement pump, featuring a simplified structure and ease of maintenance, suitable for constant-speed systems.

  • YCY Series (25YCY/40YCY): Constant pressure automatic variable control. The pump automatically reduces displacement when the system reaches the preset pressure, significantly saving energy and controlling oil temperature.

  • PCY Series: Constant power control that adjusts flow relative to load pressure, preventing prime mover overloads.

  • SCY Series: Manual variable control via handwheel, providing intuitive operation for lab equipment or simpler machinery.

• High Volumetric Efficiency: Optimized valve plate and piston clearance control maintain minimal internal leakage and superior output precision, even at peak pressures.

• Universal Compatibility: The classic CY14-1B mounting standard ensures easy interchangeability for retrofitting older machinery or integrating into new Hydraulic Power Units (HPUs).
