CP1 CP2 Hydraulic Gear Pump | CP1-25-10R CP1-40-P-10R CP1-63-P-10R-36 | High Pressure Pump

LIC Hydraulic’s CP Series (CP1, CP2) high-pressure gear pumps are engineered for applications where compact size and high-power density are critical. This series, including models like CP1-40-P-10R and CP1-63-P-10R-36, is a global standard for high-pressure industrial hydraulics. We emphasize 100% Drop-in Interchangeability, ensuring our pumps match OEM mounting patterns and efficiency curves perfectly. To guarantee field reliability, every unit undergoes 100% simulated load testing, ensuring zero-leakage and stable performance under peak pressure cycles.

Key Technical Advantages

• Extreme Pressure Resistance: Built with high-tensile housing and reinforced bearing journals, the CP1 series maintains structural integrity even during continuous 25MPa operation with minimal material fatigue.

• Superior Volumetric Efficiency: Utilizing advanced axial and radial pressure compensation, our pumps automatically adjust internal clearances, keeping volumetric efficiency above 93% throughout the service life.

• Ultra-Low Flow Ripple: The optimized involute gear geometry minimizes fluid trapping and pulsation, leading to exceptionally smooth hydraulic output and reducing operational noise by up to 8 dB.

• Advanced Wear Resistance: Gears are through-hardened and micro-finished to micron tolerances. This process enhances the pump’s resilience to oil contamination and significantly extends service intervals.

Application Areas

• Industrial Machinery: Injection molding machines, rubber processing equipment, and hydraulic balers.

• Mobile Hydraulics: Auxiliary circuits for forklifts, material handlers, and loaders.

• Power Units (HPU): Lubrication systems for machine tools and specialized lifting platforms.

Expert Maintenance Tips

• Suction Line Integrity: Given the high suction velocity, ensure all inlet seals are high-grade and vacuum-tight. Air ingress is the primary cause of cavitation and internal scoring.

• Viscosity Management: We recommend ISO VG 32 or 46 wear-resistant hydraulic oil. Keep the operating temperature within 30°C – 60°C (86°F – 140°F) for optimal seal life.

• Priming Protocol: Always fill the pump with clean hydraulic fluid before initial startup. Use an “inching” (jogging) start method for 3-5 cycles to bleed air before reaching full operational speed.
