CBN-F3/E3 Series Hydraulic Gear Pump Replacement | CBN-F314/F316 High-Pressure Pump

Genlu Hydraulic proudly introduces our industrial-grade CBN-F3 and CBN-E3 Series high-pressure gear pumps. Fully engineered to match the industry-standard CBN architecture, this series is optimized for construction, agricultural, and industrial hydraulic applications. We specifically highlight our supply capability for precision-tuned units such as the CBN-F314, CBN-E314, CBN-F316, and CBN-E316.

The CBN series is renowned for its compact design, robust high-pressure tolerance, and serviceability. Genlu guarantees 100% Drop-in Interchangeability across mounting dimensions, splined-shaft specifications, port locations, and performance curves compared to original CBN-F3/E3 assemblies. Every pump undergoes 100% full-pressure load and seal-integrity verification on our digital test benches, certifying rugged, consistent performance for your hydraulic systems.

Key Technical Advantages:

• Pressure-Balance Compensation: High-performance pressure-compensating side plates automatically adjust axial clearance, maximizing volumetric efficiency at high pressures and reducing energy waste.

• High-Strength Alloy Gears: Gears are manufactured via precision hobbing and carburizing/quenching, ensuring elite tooth-profile accuracy for smooth, low-noise engagement.

• Rugged Housing Architecture: Built with a high-strength aluminum alloy/cast-iron composite that offers an ideal balance of weight and structural rigidity, preventing deformation under 250 bar peak pressure.

• True Plug-and-Play Compatibility: Strictly compliant with original CBN interface geometry, ensuring immediate integration into existing hydraulic circuits without requiring structural modifications.

Application Areas:

• Construction Machinery: Power units for dump-truck hoists, loader steering, and forklift lift mechanisms.

• Agricultural Equipment: Tractor linkage control and power units for compact seeding/harvesting equipment.

• Industrial Equipment: Scrap-metal compactors and compact hydraulic lifting platforms.

Expert Maintenance Tips:

• Port-Seal Integrity: Cavitation caused by air ingestion is the primary killer of gear pumps. Ensure all suction-side fittings are airtight; even micro-leaks can introduce air, causing vibration and increased noise levels.

• Filtration Standards: Gear pump internals are sensitive to contaminants. Maintain system fluid cleanliness with 25μm (or finer) filtration. If pressure stability fluctuates, inspect the suction-line filter for blockages immediately.

• Corrosion Management: If equipment is idle for extended periods, flush the pump cavity with clean hydraulic fluid and seal the ports. This prevents internal oxidation/rusting, which can degrade sealing performance upon re-start.
