Product Description
The K3V180DT Charge Pump serves as a key low-pressure oil supply component within hydraulic systems. Mounted directly onto the K3V180DT main pump, it is responsible for delivering a consistent charge flow and maintaining the required charge pressure to support the main pump’s operation.
This pump works on the principle of positive displacement, utilizing the rotation and meshing of external gears to create periodic volume changes within sealed chambers, allowing hydraulic oil to be continuously drawn in and discharged.
By ensuring proper inlet conditions for the main pump, the charge pump also feeds oil to control circuits while providing essential lubrication and cooling for internal components. During prolonged heavy-duty operation, it maintains stable charge pressure, helping to avoid cavitation and oil starvation.
As a result, it minimizes wear on critical parts such as pistons, bearings, and valve plates, enhances overall system reliability and efficiency, extends the service life of the equipment, and reduces maintenance requirements and operating costs.
Low Noise & High Efficiency: Optimized gear structure delivers smooth performance with reduced noise and improved volumetric efficiency.
Enhanced Main Pump Stability: Supplies consistent charge oil flow to ensure proper lubrication and cooling of the main pump.
Extended System Lifespan: Stable oil supply minimizes component wear and helps prolong the service life of the hydraulic system.
Flexible Control Compatibility: Designed to work with various hydraulic control systems to suit different applications.

K3V180DT Charge Pump FAQ
A: The K3V180DT charge pump supplies low-pressure oil to the main hydraulic pump, ensuring proper lubrication, cooling, and stable operation of the hydraulic system.
2.What type of pump is the K3V180DT charge pump?
A:It is a gear-type charge pump, designed to provide a stable and continuous flow of charge oil for hydraulic systems.
3.Which main pump is the K3V180DT charge pump used with?
A:The K3V180DT charge pump is typically used with K3V180DT axial piston main pumps, commonly found in medium to large excavators.
4. What excavator size is this charge pump suitable for?
A: It is generally suitable for 20–35 ton class excavators, depending on the specific hydraulic system configuration.
5.What are the main advantages of the K3V180DT charge pump?
A: Key advantages include stable oil supply, low noise operation, high efficiency, compact structure, and long service life.
6.Can this charge pump replace the original OEM part?
A: Yes, it can be used as a direct replacement for OEM charge pumps, provided that the mounting dimensions and specifications match.
7.What kind of hydraulic oil should be used?
A：It is recommended to use high-quality anti-wear hydraulic oil such as ISO VG46 or VG68 to ensure optimal performance and durability.
8.What are common signs of a failing charge pump?
A：Common symptoms include insufficient pilot pressure, overheating, abnormal noise, unstable main pump operation, and reduced system efficiency.
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.
