T7G Parker Hydraulic Vane Pump – FAQ

1. What are the main features of the T7G vane pump?

The T7G series offers high pressure capability, low noise operation, stable flow output, and long service life, making it ideal for heavy-duty hydraulic systems.

2. What is the maximum operating pressure of the T7G pump?

The T7G vane pump typically supports continuous pressure up to 240–280 bar and peak pressure up to approximately 300 bar, depending on the model and working conditions.

3. Is the T7G pump interchangeable with original Parker pumps?

Yes, it is designed to be fully interchangeable, including mounting dimensions, shaft size, and port configuration, allowing direct replacement without system modification.

4. What types of hydraulic fluids can be used?

The pump is compatible with:

• Anti-wear hydraulic oil (ISO VG32, VG46, VG68)

• Some fire-resistant fluids (depending on seal material)

Proper fluid selection is essential for optimal performance and durability.

5. What are common causes of noise or vibration?

Noise and vibration may result from:

• Air entering the system (aeration)

• Cavitation due to poor suction conditions

• Misalignment of pump and motor

• Excessive wear of internal components

6. What is the recommended filtration level?

A filtration level of ≤25 μm (preferably 10–15 μm) and cleanliness level of ISO 4406 18/16/13 or better is recommended to protect internal components.

7. How can cavitation be prevented in T7G pumps?

To avoid cavitation:

• Ensure sufficient inlet pressure

• Use properly sized suction lines

• Minimize suction resistance

• Maintain proper oil level in the tank

• Avoid excessive pump speed

8. How to extend the service life of the T7G vane pump?

Best practices include:

• Keep hydraulic oil clean and within proper viscosity range

• Avoid operation beyond rated pressure

• Ensure correct installation and shaft alignment

• Regularly inspect seals and internal wear parts

• Maintain stable operating temperature

Certifications & Quality Assurance

Charge 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.

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.
