VG Series Double Pump FAQ

1.What is the VG Series Double Pump used for?

The VG Series Double Pump is widely used in construction machinery, agricultural equipment, forklifts, mining machinery, and hydraulic systems that require two independent oil flows from one drive source.

2.What are the advantages of a double pump compared with a single pump?

A double pump combines two pumps into one compact unit, helping save installation space, reduce connection components, improve efficiency, and lower overall system costs.

3.What hydraulic oil is recommended for the VG Series Double Pump?

High-quality anti-wear hydraulic oil with the correct viscosity grade is recommended. Common options include ISO VG32, VG46, or VG68 depending on the working temperature and environment.

4.Can the VG Series Double Pump support high-pressure applications?

Yes. The VG Series Double Pump is designed for stable performance under high working pressure conditions, making it suitable for demanding hydraulic applications.

5.How should the VG Series Double Pump be maintained?

Regularly check the hydraulic oil cleanliness, inspect seals and connections for leakage, replace filters on schedule, and avoid operating the pump under dry-running conditions.

6. Can the displacement combination be customized?
Yes. Different front and rear pump displacement combinations are available to meet various machine flow and pressure requirements.

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

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.
