Key Technical Advantages

1. Axial Clearance Automatic Compensation + Radial Hydraulic Balance – High Efficiency with Long Service Life

CBW/CBQ/CBF/CBN series gear pumps feature axial clearance automatic compensation and radial hydraulic balance designs. This design effectively minimizes internal leakage, maintaining high volumetric efficiency (≥90%) across all operating conditions. The axial clearance automatic compensation mechanism ensures the pump maintains high efficiency over extended service life.

2. High-Strength Aluminum Alloy / Cast Iron Body – Lightweight with Durability

The CBF, CBQ series, and select CBW models feature high-strength aluminum alloy housings, achieving lightweight construction while maintaining structural strength. The CBW series also offers cast iron housing options for more demanding operating conditions. The CBQ series offers cast iron material options as well.

3. DU Self-Lubricating Bearings with High Load Capacity

CBW/CBQ/CBF/CBN series feature DU self-lubricating bearings and floating side plates. DU bearings offer excellent self-lubricating properties and wear resistance, capable of withstanding high radial loads and ensuring long-term reliable operation under high-pressure conditions.

4. Low-Noise Operation – Improves Operator Environment

CBW/CBQ/CBF/CBN series gear pumps are renowned for high volumetric efficiency, high pressure, low noise, strong vibration resistance, and long service life. The low-noise characteristic significantly improves the equipment operator’s working environment.

5. Flexible Multi-Pump Configurations with Broad Interface Options

In addition to single pumps, CBW/CBQ/CBF/CBN series support tandem and multiple pump configurations. Inlet and outlet port connections are available in threaded, flange, and other options. Drive shaft connections are available in plain key, rectangular spline, involute spline, SAE involute spline, and other configurations.

6. Wide Speed Range with Excellent Low-Speed Performance

CBW/CBQ/CBF/CBN series offer a wide speed range, maintaining high volumetric efficiency even at low speeds of 400-800 rpm. With high operating pressure and broad speed range, these pumps flexibly adapt to various drive motors.

Expert Maintenance Tips

Model Code Verification (verify each element):

CBW/CBQ/CBF/CBN series model codes contain critical information. Before selection and installation, confirm the following:

• CBW/CBQ/CBF/CBN: Product series code.

• Pressure Grade: E = 16 MPa, F = 20-25 MPa.

• Gear Modulus: CBW modulus 3, CBF modulus 4, CBQ modulus 5, CBN modulus 5.

• Numbers: Nominal displacement (mL/r).

• Suffix: Mounting type, port type, and shaft configuration.

Verify Rotation Direction:

Confirm that the drive shaft rotation matches the direction code in the model. CBW/CBQ/CBF/CBN series offer both clockwise (R / right-hand, typically omitted) and counter-clockwise (L / left-hand) options. Incorrect rotation will prevent pressure build-up and may damage internal gears and bearings.

Mounting Flange and Drive Shaft Matching:

CBW/CBQ/CBF/CBN series offer both oval flange and square flange mounting types, with shaft options including plain key, rectangular spline, involute spline, and SAE involute spline. Verify that the equipment-side flange type and shaft specification match the pump configuration before installation.

Suction Line and Fluid Requirements:

Use mineral hydraulic oil or anti-wear hydraulic oil (CLP) meeting ISO/DIN standards. Ensure the suction line is properly sealed with no air leaks and the suction filter is not clogged. System oil cleanliness is critical—NAS Class 9 or higher is recommended.

First-Start Priming Procedure:

After new pump installation or system overhaul, ensure the pump cavity is filled with oil before first start. Jog the pump several times at low pressure and low speed to purge air from the pump, then run at no load for several minutes. Gradually increase to rated speed and working pressure only after the pump body is fully filled with oil. Running the pump dry will cause irreversible damage to gears and bearings.

Temperature and Operating Limits:

Maintain long-term operating oil temperature within 30-60°C, with maximum not exceeding 80°C. Never operate continuously beyond rated pressure and maximum speed. Suction pressure must not fall below -0.03 MPa to prevent cavitation and air entrainment.

Regular Maintenance and Inspection:

Replace hydraulic oil and return filters every 1,000 operating hours or per equipment manufacturer recommendations. Regularly inspect oil level, oil quality, and filter condition. If abnormal noise, vibration, or flow reduction is detected, shut down and inspect immediately. Maintain a clean working environment during repairs.
