CBT-F & CBF-F Series Gear Pump | CBT-F410 CBT-F425 CBT-F432 | Hydraulic Pump

LIC Hydraulic provides the CBT-F & CBF-F Series, a rugged and reliable solution for mid-to-high pressure hydraulic systems. These external gear pumps, covering displacements from $10\text{ cc}$ to $32\text{ cc/rev}$, are built with a high-strength aluminum alloy housing and feature a specialized axial clearance compensation system. Models like the CBT-F423 and CBT-F432 are engineered to maintain high efficiency even under continuous pressures of $20\text{ MPa}$ ($2900\text{ PSI}$). Known for their compact size and versatility, the CBT-F series is the primary choice for mobile applications, particularly in the agricultural and material handling industries.

Technical Specifications (Bulleted List)

• Series: CBT-F / CBF-F (High Pressure Aluminum Series).

• Displacement Range: $10, 12.5, 14, 16, 19.2, 23, 26.5, 30, 32$ ($\text{ml/r}$).

• Pressure Rating: Nominal $20\text{ MPa}$, Peak up to $25\text{ MPa}$.

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

• Mounting: Variety of shafts (Splined, Keyed) and flange options available.

Key Technical Advantages

• Self-Adjusting Floating Bushings: Automatically compensates for internal clearances based on operational pressure, ensuring maximum volumetric output throughout the pump’s life.

• Lightweight Durability: The precision-extruded aluminum body offers excellent thermal conductivity and high structural strength with minimal weight.

• High Speed Capability: Capable of operating at speeds up to $2500\text{ RPM}$, making it suitable for direct engine-driven applications.

• Multi-Fluid Compatibility: Optimized for use with standard mineral hydraulic oils (AW46/AW68).

Application Areas

• Agricultural Equipment: Lift and steering systems for tractors and specialized harvesters.

• Material Handling: Main hydraulic pumps for IC and electric forklifts.

• Truck Hydraulics: Powering hydraulic gates and auxiliary systems on utility trucks.

Expert Maintenance Tips

• Check Filtration: To protect the aluminum wear plates, maintain oil cleanliness at $ISO\text{ 19/17/14}$. Particle contamination is the #1 cause of pressure drop in gear pumps.

• Monitor Seal Health: If oil appears in the bell housing, check the pump’s shaft seal. High backpressure in the system can sometimes damage the seal on CBT-F432 models.

• Avoid Shock Loads: Ensure the system relief valve is set correctly. Operating beyond the $25\text{ MPa}$ peak pressure will lead to internal gear “scoring” and immediate loss of efficiency.
