Product Description
The PVD-0B-18P-6G3 Charge Pump functions as an important low-pressure oil supply unit in hydraulic systems. It is designed to provide the main pump with stable charge flow and charge pressure. The pump operates based on the principle of volumetric hydraulic transmission, where the meshing rotation of external gears changes the volume of sealed working chambers, enabling continuous suction and discharge of hydraulic oil.
The charge pump helps maintain favorable suction conditions for the main pump, supplies oil for system control circuits, and provides necessary lubrication and cooling for key internal components. When the main pump high-pressure circuit operates under long-term high-pressure and heavy-load conditions, the charge pump ensures a stable charge pressure supply, helping prevent cavitation and insufficient oil supply. This reduces wear and potential damage to critical components such as the pistons, bearings, and valve plate, ensuring stable and efficient operation of the entire hydraulic system, extending equipment service life, and reducing maintenance costs.
Low Noise & High Efficiency：Optimized gear design ensures smooth operation, low noise, and high volumetric efficiency.
Improve Main Pump Stability：Provides stable charge oil flow to maintain proper lubrication and cooling of the main pump.
Extend Hydraulic System Service Life：Reliable charge oil supply reduces wear and helps extend the lifespan of the hydraulic system.
Multiple Control Options：Compatible with different hydraulic control systems to meet various application requirements.

2. Which main pump is the PVD-0B-18P-6G3 charge pump compatible with?
This charge pump is typically mounted on and used with the PVD-0B-18P series main hydraulic pumps, ensuring seamless integration and stable performance.
3. What type of pump is the PVD-0B-18P-6G3?
It is an external gear pump that operates based on volumetric displacement principles, providing continuous and stable oil flow.
4. What are the main application scenarios?
The PVD-0B-18P-6G3 charge pump is widely used in construction machinery such as hydraulic excavators, where reliable charge pressure is critical for system efficiency.
5. What are the advantages of this charge pump?
Key advantages include compact structure, stable flow output, high reliability, easy installation, and cost-effective maintenance.
6. What happens if the charge pump fails?
If the charge pump fails, the main pump may suffer from insufficient oil supply, leading to cavitation, overheating, reduced efficiency, and potential damage to hydraulic components.
7. Is this product an original or replacement part?
The PVD-0B-18P-6G3 charge pump can be provided as a high-quality replacement part with performance and dimensions equivalent to the original, but at a more competitive price.
8. How to maintain the charge pump for longer service life?
Regularly check hydraulic oil cleanliness, maintain proper oil levels, replace filters on time, and avoid operating under extreme conditions to ensure long service life.
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.
