CBF-F4 Series Hydraulic Gear Pump: High-Efficiency Aluminum Hydraulic Power for Heavy Equipment
When selecting hydraulic fluid power components for mobile machinery, mechanical engineers require reliable pressure generation, long service life, and lightweight durability. The CBF-F4 Series Hydraulic Gear Pump is a high-performance single hydraulic pump manufactured with a high-strength aluminum alloy casing. Integrating advanced axial clearance floating compensation, radial balance, and DU self-lubricating bearings, the CBF-F4 series delivers high volumetric efficiency (≥90% to 93%), low operational noise, and exceptional vibration resistance across heavy-duty industrial and agricultural applications.

Key Advantages
1. High Volumetric Efficiency & Floating Clearance Compensation
Utilizing dynamic axial clearance floating offset technology and radial hydraulic balance, the CBF-F4 maintains a consistent volumetric efficiency above 90% to 93% even under continuous high-pressure loads. This minimizes internal bypass and oil heating.
2. Premium Die-Cast Aluminum Body with DU Self-Lubrication
Built with a high-strength aluminum alloy casing, the pump offers a lightweight footprint (3.2 kg to 4.7 kg) while providing excellent fatigue resistance. Integrated DU self-lubricating sleeve bearings ensure reduced mechanical friction and quiet operation.
3. Versatile Mounting & Port Options
Designed for universal machinery compatibility, the CBF-F4 supports both flat spline shafts and rectangular spline shafts, along with standard screw-threaded ports (M22x1.5, M27x2, M33x2) or split flange connections.
CBF-F4 Pump Applications
Due to its high pressure rating (up to 25 MPa) and broad displacement spectrum (10 to 50 mL/r), the CBF-F4 series is widely specified across multiple industries:
- Material Handling & Construction: Forklifts, loading trucks, excavators, hoists, and road rollers.
- Mining & Heavy Equipment: Mining transport machinery and mobile crushers.
- Agricultural & Municipal Machinery: Tractors, harvesters, sanitation trucks, and light industrial power units.

Frequently Asked Questions (FAQ)
1.What is the maximum pressure limit of the CBF-F4 Series Hydraulic Gear Pump?
For models from 10 to 32 mL/r, the CBF-F4 Hydraulic Gear Pump features a rated pressure of 20 MPa (200 bar) and a maximum pressure limit of 25 MPa (250 bar). For larger 40 and 50 mL/r models, the rated pressure is 16 MPa with a max pressure limit of 20 MPa.
2. How do I specify the correct shaft extension and rotation for my replacement pump?
Refer to the model code: select P for a flat plain shaft or H for a rectangular spline shaft. For rotation, specify L for counterclockwise (Left) or R for clockwise (Right, viewed from shaft end).
3. What hydraulic oil cleanliness is required for the CBF-F4 series?
The pump operates best with mineral-based hydraulic oil (viscosity 20–43 mm²/s) and requires a system oil filtration accuracy of $\le 25\ \mu\text{m}$ to prevent internal wear on DU bearings
