CBS/F-D300 Series Bidirectional Compound Gear Pump FAQ

1.  What makes the CBS/F-D300 pump different from standard gear pumps?

The CBS/F-D300 series supports bidirectional rotation and flow output, allowing the hydraulic system to operate in forward and reverse directions, which standard single-direction gear pumps cannot achieve.

2. What hydraulic oil is recommended?

Anti-wear hydraulic oil with proper viscosity is recommended, such as ISO VG32, VG46, or VG68 depending on the operating temperature and environment.

3. What industries commonly use this pump?

It is commonly used in construction, agriculture, mining, lifting equipment, transportation machinery, and industrial automation systems.

4. Can the pump be customized?

Yes. Different shaft types, flange configurations, mounting styles, and port connections are available according to customer requirements.

5. What is the maximum operating pressure?

The typical rated pressure is around 10 MPa, while the maximum pressure can reach approximately 12.5 MPa depending on the specific model. 

6. Does the pump support high-speed operation?

Yes. Depending on the model, the maximum operating speed can reach around 2500 r/min while maintaining stable performance. 

7. What are the installation requirements for VVS pumps

Standard mounting: ISO 3019/2 or SAE flange

Rotation direction: right-hand (clockwise)

No radial or axial load should be applied to the shaft

Proper installation is critical for performance and durability.

8. What applications are VVS variable vane pumps commonly used in

They are widely used in:

CNC machine tools

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
