CBN High Pressure Gear Pump | CBN-F320-AFP | CBN-F325-AFP | CBN-E(F)320 Hydraulic Pump

The CBN Series Gear Pump from LIC Hydraulic is a highly reliable power source for mobile and industrial hydraulic systems. Featuring a high-strength aluminum alloy body and axial pressure compensation technology, models like the CBN-F320-AFP and CBN-F308-AFPR deliver exceptional performance under high-pressure conditions. Designed for versatility, these pumps are widely used in agricultural machinery and material handling equipment. We offer 100% drop-in replacements, ensuring consistent flow and durability for your demanding work environments.

Technical Highlights

• Series: CBN (High Pressure Aluminum)

• Pressure Ratings: $16\text{ MPa}$ (E Grade) / $20\text{ MPa}$ (F Grade)

• Displacement Range: $4\text{cc}$ to $25\text{cc/rev}$

• Efficiency: $\ge 92\%$ Volumetric Efficiency

• Mounting: SAE or standard diamond 2-bolt flange

• Shaft: Rectangular spline, keyed, or tapered options.

Core Advantages

• Floating Bushing Design: Automatically compensates for internal clearances based on operational pressure, maintaining peak efficiency throughout the pump’s lifecycle.

• Fatigue-Resistant Body: The aluminum extrusion housing is engineered to handle constant pressure pulsations without structural failure.

• Robust DU Bearings: High-quality composite bushings provide superior support for the gear journals, reducing noise and increasing service life under heavy radial loads.

• Compact & Lightweight: The optimized power-to-weight ratio makes it the ideal choice for mobile applications where space is at a premium.

Expert Maintenance Tips

• Rotation Verification: Before installation, always verify the pump’s rotation (Left or Right) against the motor’s drive. Running a pump in the wrong direction will damage the internal seals instantly.

• Suction Filtration: To prevent debris from scoring the aluminum housing, use a $100\mu\text{m}$ suction strainer and ensure the oil tank is free from metal particles.

• Priming: Never start the pump dry. Fill the intake port with clean hydraulic oil and rotate the shaft by hand to ensure internal lubrication before power-up.
