Key Technical Advantages

1. Medium-to-High Pressure Capability – 25MPa Rated Pressure
The CBFZ-F23 delivers a rated pressure of 25 MPa (approx. 250 bar) . The high-strength cast iron housing and precision-machined gears ensure long-term stability under high-pressure conditions.

2. High-Strength Cast Iron Housing – Durable & Reliable
The pump housing is manufactured from high-strength cast iron, providing excellent fatigue strength and impact resistance. Particularly suitable for forklifts and construction machinery operating under harsh conditions over extended periods.

3. High Volumetric Efficiency & Long Service Life
The CBFZ series gear pumps deliver high working pressure, high volumetric efficiency, and long service life. Optimized gear design and precision machining effectively reduce internal leakage and improve overall efficiency.

4. Low Noise & Compact Design
The CBFZ series gear pumps feature low noise, small size, and easy installation. The compact design makes it particularly suitable for forklifts and equipment with limited installation space.

5. Wide Temperature Range Adaptability
Operating temperature range of 30 – 90℃ accommodates various seasonal and operational temperature requirements for forklifts and construction machinery.

6. 100% Factory Tested & Direct Interchangeability
Every unit undergoes 100% workload simulation testing prior to shipment, covering pressure retention verification, internal leakage detection, and flow validation. Fully compliant with CBFZ series original design standards, with flange dimensions and mounting interfaces identical to OEM pumps—direct drop-in replacement with zero modifications required.

Application Areas

The CBFZ-F23 gear pump is primarily used in the following equipment:

• Forklifts: Various forklift hydraulic lifting systems and steering systems

• Construction Machinery: Loaders, excavators, and other construction equipment

• Lifting & Transport Machinery: Cranes, lift platforms

• Road Construction Machinery: Road rollers, pavers, and other road construction equipment

• Environmental Machinery: Refuse compactors and other environmental equipment

Expert Maintenance Tips

1. Model Confirmation
The CBFZ-F23 offers 23 ml/r displacement. The CBFZ series also includes CBFZ-F25 (25 ml/r), CBFZ-F28.2 (28.2 ml/r), CBFZ-F30 (30 ml/r), CBFZ-F32 (32 ml/r), and other displacement options. Before installation, confirm the correct displacement based on system flow requirements and verify the complete model code on the pump nameplate.

2. Rotation Direction Confirmation
The CBFZ series supports both clockwise and counter-clockwise rotation configurations. Before installation, always verify that the PTO rotation direction of the host machine matches the pump’s rotation direction—incorrect rotation will result in pump failure to prime and may cause severe damage to gears and bearings within a short period.

3. Installation Precautions

• Thoroughly clean the mounting flange and shaft mating surfaces before installation to ensure no debris remains

• Mounting type is flange mounting—use specified torque values for mounting bolts

• Ensure correct connection of inlet and outlet ports—the inlet line must have no restrictions or sharp bends

• Ensure hydraulic system fluid cleanliness meets requirements

4. First Start-Up and Bleeding

• Before first start-up, must fill the pump with hydraulic oil through the inlet port—never start dry

• After start-up, run at low speed with no load for 2–3 minutes to ensure complete air evacuation from the system

• Check for abnormal noise or leakage

5. Fluid and Filtration

• Use high-quality anti-wear hydraulic oil compliant with standards

• Maintain operating temperature within 30 – 90℃

• Maintain system oil cleanliness to ISO 4406 18/15 or better

• Regularly replace return line filters to prevent contaminants from entering the pump

6. Periodic Maintenance

• Check mounting bolt torque every 1,000 operating hours

• Regularly monitor system operating pressure—not to exceed 25 MPa rated pressure

• Regularly inspect shaft seals to prevent leakage

• If flow output decreases, noise levels increase abnormally, or system temperature rises excessively, inspect and replace worn components promptly
