CY14-1B Series Hydraulic Pump | 2.5MCY, 63YCY | 31.5MPa Axial Piston Pump

CY14-1B Series High-Pressure Axial Piston Variable Pump

Product Overview: The CY14-1B series is a foundational pillar in industrial high-pressure hydraulic technology, utilizing a robust swashplate-type axial piston design. This series covers a wide spectrum of displacements, from the ultra-compact 2.5cc to the mid-to-large 63cc units. Depending on the control modulation, the MCY series provides stable fixed displacement delivery, while the YCY series offers manual pressure-compensated variable output. With a rated pressure of 31.5MPa, it is the premier choice for machine tool hydraulics, forging equipment, marine systems, and high-pressure Hydraulic Power Units (HPU).

Key Technical Advantages:

• Heavy-Duty High-Pressure Performance: Engineered for continuous high-pressure load cycles. Rated at 31.5 MPa (315 Bar) with peak cycles up to 40 MPa, maintaining peak volumetric efficiency under extreme load conditions.

• Versatile Variable Control (YCY/SY):

  • SY-63YCY14-1EL: This model integrates manual variable adjustment with electro-hydraulic (EL) characteristics, allowing operators to precisely modulate flow and pressure for maximum energy efficiency.

  • 2.5MCY14-1B: A highly compact fixed displacement design ideal for lubrication, cooling, or small-scale hydraulic drives requiring precise, low-flow delivery.

• Contamination Resistance & Durability: The classic axial piston architecture is less sensitive to fluid cleanliness. All internal components are hardened for superior wear resistance, significantly extending service life under heavy duty.

• Standardized Industrial Design: Manufactured to strict industrial standards for mounting flanges, shaft ends, and porting, making it a cost-effective solution for legacy system upgrades and direct spare part replacements.
