Product Description
The 4520VQSV10 China Double Vane Pump is a high-performance hydraulic pump designed for industrial and mobile hydraulic systems requiring dual-flow output and reliable operation. Its robust construction and precision components ensure stable pressure, smooth flow, and long service life, making it ideal for multi-circuit systems and demanding hydraulic applications.
High Volumetric Efficiency – Reduced internal leakage ensures maximum oil delivery.
Low Noise & Vibration – Optimized internal design for quiet operation.
Durable Construction – Wear-resistant vanes and high-strength materials extend service life.
Compact Design – Saves space and allows flexible installation.
Stable Performance – Maintains consistent flow and pressure under varying load conditions.
Flexible Compatibility – Works with standard hydraulic oils (ISO VG32–68).
The 4520VQSV10 Double Vane Pump needs correct rotation for stable and efficient operation.
Direction: Follow the arrow on the pump (clockwise or counterclockwise).
Vane Movement: Vanes slide outward as the rotor turns, creating sealed chambers for continuous oil flow.
Dual-Pump Sections: Both sections rotate together for balanced dual-flow output.
Tips: Check shaft alignment and drive direction before start-up; do not run in reverse unless allowed.
Benefits: Ensures smooth flow, low noise, reduced wear, and long service life.
Correct rotation is essential for reliable dual-flow hydraulic performance.

Charge 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.
It is a double vane hydraulic pump with two pump sections, providing dual-flow output.
2. What are the advantages of the double vane design?
It allows independent or combined flow, supports dual circuits, and improves system efficiency.
3. What hydraulic oil is recommended?
Use anti-wear hydraulic oil such as ISO VG32, VG46, or VG68.
4. What is the maximum working pressure?
Typically up to 16–20 MPa, depending on operating conditions.
5. Can the pump run continuously?
Yes, it is designed for continuous operation with stable performance.
6. Is rotation direction important?
Yes, correct rotation is critical. Wrong direction may cause low performance or damage.
7. What are the main applications?
Widely used in machine tools, injection molding machines, hydraulic power units, and industrial automation systems.
8. Is it a good replacement for original pumps?
Yes, it can be a cost-effective alternative to many standard vane pumps with similar specifications.
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.
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.
