A4VG71 hydraulic charge pump FAQ 

1. What is the function of the A10VGT090 hydraulic charge pump?

The A10VGT090 hydraulic charge pump is designed to supply low-pressure oil to the main hydraulic pump in a closed-loop system. It ensures sufficient oil replenishment, maintains system pressure, and prevents cavitation.

2. What type of hydraulic system is the A10VGT090 charge pump used in?

It is mainly used in closed-loop hydraulic systems, especially in mobile machinery such as excavators, loaders, and road construction equipment.

3. How does the A10VGT090 charge pump work?

The pump operates based on the gear pump principle. As the gears rotate, they create a vacuum at the inlet, drawing in hydraulic oil, and then push the oil to the outlet to provide a stable charge flow.

4. What are the main advantages of the A10VGT090 charge pump?

Key advantages include compact structure, stable oil supply, high reliability, low noise operation, and easy installation and maintenance.

5. What could happen if the charge pump fails?

If the charge pump fails, it may lead to insufficient oil supply, resulting in cavitation, overheating, reduced efficiency, and potential damage to the main hydraulic pump.

6. How to maintain the A10VGT090 hydraulic charge pump?

Regular maintenance includes checking oil cleanliness, replacing hydraulic filters, inspecting seals and gears for wear, and ensuring proper oil levels to extend service life.

7. Can the A10VGT090 charge pump be replaced with an alternative model?

Yes, it can be replaced with compatible models that match the original specifications in terms of displacement, mounting dimensions, and pressure ratings.

8. What factors should be considered when selecting an A10VGT090 charge pump?

Important factors include system pressure requirements, flow rate, compatibility with the main pump, installation space, and operating environment.

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.
