FAQ:

Can the A2FO unit work as a hydraulic motor?

Yes. The A2FO series axial piston element can function as a hydraulic motor in a hydrostatic transmission. When operating as a motor :

• The output speed is proportional to the flow rate and inversely proportional to its displacement.

• The output torque increases with the pressure difference between the high-pressure and low-pressure sides.

3. What are the common application areas for A2FO pumps?

A2FO pumps are widely used in the hydraulic systems of various mobile and industrial machinery, including but not limited to :

• Engineering Machinery: Concrete pump trucks (boom pumps), cranes, excavators, mining machinery.

• Construction and Transportation Machinery: Mixer trucks, lifting and transport machinery.

• Industrial Applications: Metal forming, plastics, steel plants, mining, oil and gas, wind power.

4. What are some common models of the A2FO series?

The A2FO series includes a wide range of models with different displacements. Some frequently mentioned models include :

• A2FO23/61L-PPB06

• A2FO32/61L-PAB05

• A2FO63/61R-PBB05

• A2FO80/61R-VPB05

• A2FO160/61R-PBB05

The series covers sizes from 5 to 1000 .

5. Is the A2FO pump suitable for excavator applications?

Yes, the A2FO series is commonly used in excavators and other construction machinery. For instance, models like the A2FO63 are specified as hydraulic pumps for excavators . Their robust design and high-pressure capability make them suitable for the demanding conditions of excavator operation.

6. What about after-sales service, warranty, and repair?

Information regarding service and warranty varies by supplier. It is essential to confirm these terms with your specific supplier.

• Warranty: Some suppliers offer a warranty period for their products or repair services. For example, one source mentions a half-year warranty for a new A2FO63 pump, while another mentions a one-year warranty for a repaired unit .

• Repair Services: Professional repair services are available from specialized companies. These services often include a full diagnosis, part replacement, and performance testing on a test bench to ensure the unit meets original factory specifications. Typical repair turnaround can be 1-3 working days, and repaired units often come with a warranty, such as one year .
