PVD-2B-50P-20G5 Charge Pump FAQ 

1.Do I need to install the PVD-2B-50P-20G5 Charge Pump separately? What should I pay attention to when replacing it?

No separate installation needed, it is integrated with the main pump.

Align spline shaft accurately, fasten bolts with specified torque, keep fitting surface clean and fit proper seal ring to prevent oil leakage.

2.What preparations are needed before starting the PVD-2B-50P-20G5 Charge Pump for the first time?

Inspect pipe connections for no leakage. Fill qualified hydraulic oil to standard level. Verify correct rotation direction and vent internal air. Check solid installation and intact filters prior to startup.

3.What are the requirements for hydraulic oil when using the PVD-2B-50P-20G5 Charge Pump?

Use ISO VG46 or VG68 anti-wear hydraulic oil. Operating temperature ranges from -20°C to 80°C. Keep oil clean and avoid mixing different oil grades.

4. Can the rotation direction of the  PVD-2B-50P-20G5 Charge Pump be reversed? What are the consequences of reverse rotation?

Reverse rotation is not allowed. It causes insufficient oil supply, pressure decline, serious cavitation and rapid wear, resulting in pump damage.

5. Is the PVD-2B-50P-20G5 Charge Pump a dedicated accessory? Can it work normally without it?

It is a dedicated matching accessory. The whole system cannot run properly without it, and hydraulic components will be damaged easily.

6.Can the displacement of the PVD-2B-50P-20G5 Charge Pump be replaced arbitrarily?

The displacement cannot be replaced randomly. It must match original parameters. Improper displacement will trigger pressure abnormalities, poor lubrication and part damage.

Certifications & Quality Assurance

PVD-2B-50P-20G5 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.
