CBN-E316 High Pressure Gear Pump CBN Series

Product Overview

The CBN-E316CFHL (and related models CBN-E318, CBN-F310, CBT-F304, CBW, CBQ, CBF series) is a high-pressure external gear oil pump from the CBN series. Featuring a high-strength aluminum alloy housing and floating bushings for axial compensation, it offers compact size, light weight, high efficiency, low noise and long service life. Rated pressure ranges from 16–20 MPa with maximum pressure up to 25 MPa. Manufactured to OEM standards for direct bolt-on interchangeability and subjected to 100% simulated duty testing, these pumps are widely used in construction, agricultural and industrial hydraulic systems.

Key Technical Advantages

1. True drop-in interchangeability: Manufactured to OEM dimensional and porting standards for bolt-on replacement without modifications.
2. Axial floating compensation: Floating bushings effectively reduce internal leakage and maintain high volumetric efficiency.
3. Lightweight high-strength design: Aluminum alloy housing provides high pressure capability with low weight for compact installations.
4. High efficiency and low noise: Precision gear machining ensures smooth, quiet operation and reliable performance.
5. 100% simulated duty testing: Full pressure, flow, noise and endurance verification before shipment ensures ready-to-install reliability.

Application Areas

• Construction machinery auxiliary hydraulic systems
• Agricultural machinery and tractors
• Lifting, transport and mining machinery
• Automotive and industrial automation hydraulic systems
• Open-circuit systems requiring compact high-pressure gear pumps

Expert Maintenance Tips

• Confirm rotation direction and flange/shaft compatibility before installation; use recommended hydraulic oil and maintain cleanliness (filtration ≤25 μm).
• Start at low speed unloaded; check for leaks and noise. Avoid simultaneous maximum pressure and maximum speed.
• Regularly inspect seals and bearings; ensure unrestricted suction lines to prevent cavitation.
• Keep oil temperature within –20 to +80 °C; avoid over-pressure operation.
• For special codes, verify the complete order code and consult technical support.
