CY14-1B Axial Piston Pump | 160CCY14-1B 160YCY14-1B Hydraulic Pump

Genlu Hydraulic proudly introduces our CY14-1B Series high-pressure axial piston hydraulic pumps. Serving as one of the most resilient and industry-proven legacy power sources in fluid engineering, this series is widely integrated into heavy-duty forging presses, machine tool drives, metallurgical equipment, and centralized hydraulic power units (HPUs). Genlu delivers precision-engineered, drop-in replacement solutions for the complete CY14-1B lineage, spanning displacement footprints of 1.25, 2.5, 5, 10, 25, 40, 63, 80, 100, 160, and 250 cc/rev. We specialize in cross-referencing high-demand 160-frame control variants, including 160CCY14-1B (Fixed Displacement), 160YCY14-1B (Constant Power Control), 160SCY14-1B (Manual Wheel Control), 160PCY14-1B (Pressure Compensated Control), and 160MYCY14-1B (Remote Pressure Compensated Control).

Genlu’s CY14-1B piston pumps faithfully preserve and enhance the original hydro-static balance optimization between the cylinder block and the valve plate interface. We guarantee 100% Drop-in Interchangeability across standard industrial mounting flanges, straight keyed or splined input drive shafts, fluid port configurations, and distinct control module mount interfaces. Every pump undergoes a rigorous 100% full-pressure load threshold analysis and volumetric optimization evaluation in our diagnostic laboratory, assuring unwavering power delivery under continuous high-pressure industrial duty cycles.

Key Technical Advantages:

• Hydro-Static Fluid Film Balance Optimization: The critical running boundary between the rotating cylinder block and the stationary flat/spherical valve plate is engineered via sophisticated hydrostatic balance ratios. Genlu implements specialized bimetallic sintering or high-hardness bronze overlays that maintain a micron-level lubricating film under high pressures, reducing friction coefficients and boosting mechanical efficiency.

• High-Tensile Center Spring & Retainer Rigidity: Features a rugged centrally located coil spring mechanism that exerts constant forcing tension on the piston shoe retaining plate. This configuration counteracts inertia forces during rapid high-speed revolutions, preventing slipper detaching or skewing from the swashplate, which drastically increases cavitation resistance.

• Comprehensive Control Integration Adaptability: Genlu delivers optimized, responsive displacement regulation modules. The YCY constant power control tracks downstream system load variations dynamically to clip flow output along a smooth hyperbola, preventing prime mover overload; meanwhile, the PCY pressure compensator exhibits sharp, millisecond-level deadhead response for enhanced system energy savings.

• Heavy-Wall Nodular Iron Fatigue-Resistant Housing: The outer shell is cast from advanced high-density nodular iron. The thickened casing profiles easily absorb structural dynamic pressure surges up to 40 MPa without micro-fissuring, while dampening high-frequency internal rotational vibration for quiet open-floor operation.

Application Areas:

• Heavy-Duty Forging & Stamping Presses: Primary hydraulic driving pump stacks for industrial sheet metal presses, rapid stamping units, heavy profile bending machinery, and scrap metal balers.

• Precision Industrial Machine Tools: Hydrostatic power loops for heavy-duty gantry milling systems, horizontal broaching machines, and high-load deep-hole drilling stations.

• Primary Metallurgy & Mining Machinery: Actuator power supplies for blast furnace mud guns, heavy rolling mill auxiliary manifolds, and large hydraulic mine-hoist brake controls.

Expert Maintenance Tips:

• Mandatory Initial Housing Pre-Fill: Axial piston architectures feature highly loaded sliding friction pairs that cannot survive dry running. Prior to commissioning, you MUST fill the pump interior completely with clean hydraulic oil through the uppermost case drain hole until fluid flows outward. Jog the electric motor sequentially to ensure full venting before shifting to continuous speed.

• Enforce Independent Case Drain Plumbing: The case drain line must be plumbed independently straight back to the reservoir oil pool below the fluid line. Never connect this line to inline filtration units, check valves, or standard system return lines. Ensure internal housing static back-pressure remains consistently below 0.1 MPa to safeguard the shaft lip seal from high-pressure extrusion.

• Rigid Particle Fluid Contamination Control: The dynamic clearance between the pistons and cylinder bores is manufactured to micron tolerances; ambient micro-debris will scuff sliding faces, leading to rapid volumetric decay. Condition all working fluids strictly to ISO 4406 19/16/13 or tighter, and execute routine oil analyses to check for oxidation or fluid degradation.
