Products Description
Product Definition
The CBF-F4 Series High-Pressure Single Gear Pump is a precision-engineered hydraulic power component designed to convert mechanical energy from a rotating shaft into fluid flow under high pressure. It serves as the primary power source for hydraulic cylinders, motors, and actuators in demanding construction, material handling, and agricultural environments.
Working Principle
This pump operates on the fundamental principle of positive displacement. As the precision-machined gears rotate within the tightly sealed housing, the meshing teeth disengage on the suction side, creating a localized partial vacuum. This vacuum draws hydraulic fluid into the pump cavity from the reservoir. The fluid is then trapped between the gear teeth and the housing wall, transported around the periphery, and forcibly expelled through the outlet port as the gears re-engage. This continuous cycle delivers a steady and smooth flow of pressurized oil.
Features & Technical Advantages
Ultra-High Efficiency: The axial floating compensation mechanism ensures that the pump maintains a volumetric efficiency of 92% - 93% across its operating range. This superior efficiency minimizes internal slippage and energy loss, directly translating to lower hydraulic oil temperatures, reduced cooling demands, and significant fuel savings for mobile machinery.
Superior Durability: The radial balance design and DU bearings work in concert to distribute mechanical stress evenly. This robust construction ensures stable performance and reliable operation even when continuously operating at maximum peak pressures of 25 MPa, significantly reducing the risk of catastrophic breakdowns.
Low Noise Operation: By utilizing optimized gear tooth profiles and precisely machined housing chambers, fluid turbulence and pressure pulsations are minimized. This results in remarkably quiet operation, a critical feature for improving operator comfort and reducing noise pollution in enclosed cabins (such as forklifts and tractor cabs).
Wide Speed Range: The advanced bearing design and efficient suction capability allow the pump to operate seamlessly across a very broad speed range-from 600 r/min up to 3000 r/min. This flexibility makes it highly adaptable to varying engine speeds and diverse hydraulic system requirements.

Parameter Interpretation for Selection:
Displacement, 10~50 mL/r: This determines the flow rate output per rotation. For example, if your system requires faster cylinder actuation on a large excavator, choose higher displacement models (e.g., CBF-F440/450). For compact applications (e.g., mini tractors), the 10-20 mL/r range is ideal.
Pressure, Rated 16~20 MPa: The Rated Pressure indicates the safe continuous operating limit. The Max Pressure (25 MPa on most models) provides an essential safety margin for momentary hydraulic shocks or sudden heavy loads.
Speed, 600~3000 r/min: The minimum speed (600 r/min) ensures sufficient oil film is maintained to prevent dry-running. Exceeding the maximum speed can cause cavitation (erosion) and overheating.
Operating Conditions:
Hydraulic Oil: 20 - 43 cSt (Use standard mineral-based hydraulic oils like ISO VG 32 or 46).
Working Temperature: -20°C to 80°C.
Filtration Accuracy: ≤ 25 μm (Maintaining clean oil is critical for prolonging gear and bearing life).
Dimensional & Interface Options:
Shaft Options: We offer Plain Key Shaft, Rectangular Spline Shaft (for high torque), and Screw Thread Shaft to accommodate different couplings.
Port Options: Available in both Standard Threaded connections (e.g., M22x1.5, M33x2) and Flange connections (with specific bolt circle diameters for easy installation).
Mounting: Standard flange mounting with 4-M10 threaded holes.
Application
Target Industries:
Construction Machinery: Specifically designed for excavators, wheel loaders, and road rollers, handling high lift forces and continuous travel operations.
Material Handling: Core component for forklifts and aerial work platforms, providing the precision flow control needed for smooth lifting and lowering.
Agricultural Equipment: Ideal for tractors and combine harvesters, where the robust sealing protects internal parts from dust and debris commonly found in field conditions.
Mining and Hoisting: Reliable power for conveyor drives and hoists that require constant, heavy-load operation in demanding environments.
Typical Application Scenarios:
In a Forklift Hydraulic System: The CBF-F4 Series High-Pressure Single Gear Pump provides pressurized fluid to the lifting cylinders. Its high volumetric efficiency ensures the lifting speed remains consistent even as hydraulic oil temperatures rise during an extended work shift. Furthermore, the low noise feature significantly enhances the cabin environment for the driver.
In a Wheel Loader: The pump drives the hydraulic steering and boom actuation systems. The radial balance design ensures the pump can handle the high intermittent pressures encountered during heavy scooping, preventing bearing failures and minimizing downtime.
