Key Characteristics:

• The front and rear oil pumps adopt floating flower coupling structure, with a unique grease formula to ensure stable performance, long life and low noise of the oil pump;

• The maximum displacement can be extended to 320cc, which provides enough choice space for motor and driver selection and model selection;

• The direction of oil outlet and suction outlet of oil pump is flexible and easy to install;

• Any displacement combination, to meet the needs of different working conditions.

Application

Packaging & Delivery

Gear pumps are typically packaged securely to prevent damage during transit. The packaging includes:

Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.

Certifications & Quality Assurance

All vane pumps are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.

VG Serise Double Gear Pump FAQ

1.What is a VG Series Double Gear Pump?

VG Series Double Gear Pump consists of two gear pump sections integrated into one housing and driven by a single shaft, providing two independent hydraulic flow outputs.

2.What are the main advantages of a double gear pump?

• Supplies two independent hydraulic circuits

• Compact design saves installation space

• More cost-effective than using two separate pumps

• Simple structure with reliable performance

  
  

3. What applications is the VG Series pump suitable for?

It is widely used in construction machinery, agricultural equipment, commercial vehicles, and industrial hydraulic systems where dual-flow supply is required.

4. Can the two pump sections have different displacements?

Yes, the two sections can be configured with different displacements to meet various flow requirements for different hydraulic circuits.

5. What is the typical working pressure range?

VG Series pumps are generally designed for medium-pressure applications, typically up to around 20–25 MPa, depending on the specific model.

6. Are the two pump sections completely independent?

Yes, each section has its own inlet and outlet port, allowing independent operation of two hydraulic circuits, although both are driven by the same shaft.

7. What type of hydraulic oil is recommended?

It is recommended to use standard anti-wear hydraulic oil (e.g., ISO VG32, VG46, VG68) with proper filtration to ensure long service life.

8. Can VG Series pumps replace piston pumps?

No. Gear pumps are fixed displacement and are suitable for medium-pressure systems. They cannot replace piston pumps in high-pressure or variable flow applications.
