CBW-F310-CFHL CBW-F314-CFHL CBW-F316-CFHL Gear Pump 20MPa

Product Overview

The CBW-F310-CFHL, CBW-F314-CFHL and CBW-F316-CFHL belong to the CBW-F3 series of high-strength aluminum external gear pumps designed for medium-to-high pressure hydraulic systems. Featuring precision gears, floating bushings and DU self-lubricating bearings with axial clearance automatic compensation and radial hydraulic balance, these pumps deliver high volumetric efficiency, low noise and long service life. Manufactured to strict industry-standard specifications, they offer 100% drop-in interchangeability in mounting flange, shaft and ports for direct replacement without system modification. Every unit undergoes 100% simulated duty-cycle testing to ensure reliable performance in construction, agricultural and industrial equipment.

Key Technical Advantages

• High-strength aluminum housing combined with axial clearance automatic compensation maintains high volumetric efficiency over long service life, even after wear.
• Radial hydraulic balance design and DU self-lubricating bearings significantly reduce bearing loads and friction, enhancing vibration resistance and durability.
• Precision-machined gears with optimized tooth profile effectively lower operating noise and pressure pulsation for improved system comfort.
• Standardized rectangular flange, spline shaft and flange ports provide true drop-in interchangeability, simplifying installation and reducing maintenance costs.
• 100% simulated duty-cycle testing ensures reliable performance across wide speed ranges and medium-to-high pressure conditions in demanding environments.

Application Areas

Forklifts, loaders, excavators, cranes, road rollers and other construction machinery; agricultural equipment; mining machinery; light industrial machines; sanitation vehicles; and various industrial hydraulic power systems.

Expert Maintenance Tips

Ensure proper alignment of the rectangular flange and spline shaft during installation; use suitable couplings to avoid additional loads. Maintain fluid cleanliness at ISO 4406 19/17/13 or better and use mineral-oil based hydraulic fluid within recommended viscosity range. Fully bleed the system and confirm adequate suction conditions before initial start-up. Periodically inspect shaft seals and port seals; avoid contaminated or low-viscosity fluids. During cold starts, build speed and pressure gradually to establish a proper lubricating film. Avoid continuous operation beyond rated pressure or speed to maximize service life.
