Product Description of Excavator Hydraulic Axial Piston Pump MVP48.45 For LiuGong 950~970
1. Introduction
The Excavator Hydraulic Axial Piston Pump MVP48.45 is a high - performance hydraulic component designed specifically for LiuGong 950 - 970 series excavators. As a crucial part of the excavator's hydraulic system, the pump plays a vital role in ensuring the smooth operation and high - efficiency work of the excavator. With its advanced design and excellent manufacturing technology, this pump offers reliable performance and long - term durability, meeting the rigorous demands of modern construction projects.
2. Product Features
2.1 High - efficiency Hydraulic Performance
- High Flow Rate: The MVP48.45 is engineered to provide a high flow rate, which is essential for the rapid movement of the excavator's working components such as the boom, arm, and bucket. A high flow rate enables faster cycle times, increasing the productivity of the excavator. For example, during earth - moving operations, the quick extension and retraction of the boom and arm can be achieved, reducing the time required for each digging cycle.
- Precise Pressure Control: It has precise pressure control capabilities. The pump can accurately adjust the hydraulic pressure according to the actual working conditions of the excavator. Whether it is a light - duty operation like leveling the ground or a heavy - duty task such as breaking rocks, the pump can provide the appropriate pressure to ensure the efficient operation of the hydraulic actuators. This not only improves the work quality but also protects the hydraulic system from over - pressure damage.
2.2 Advanced Design
- Axial Piston Structure: The axial piston structure of the MVP48.45 is a key factor in its high - performance operation. This design allows for a more compact and lightweight pump compared to some other types of hydraulic pumps. The axial arrangement of the pistons enables smooth and continuous rotation, reducing vibration and noise during operation. In addition, the axial piston structure is more efficient in converting mechanical energy into hydraulic energy, resulting in higher overall system efficiency.
- Robust Construction: The pump is built with a robust housing made of high - quality materials. The housing is designed to withstand high pressures and harsh working environments. It can resist impacts, vibrations, and corrosion, ensuring the long - term reliability of the pump. The internal components, such as the pistons, cylinders, and valves, are also made of wear - resistant materials, which can significantly extend the service life of the pump.
2.3 Energy - Saving Design
- Variable Displacement Technology: The MVP48.45 is equipped with variable displacement technology. This means that the pump can adjust its displacement according to the load requirements of the hydraulic system. When the excavator is performing light - load operations, the pump can reduce its displacement, consuming less energy. Conversely, when heavy - load operations are required, the pump can increase its displacement to provide sufficient power. This energy - saving feature not only reduces fuel consumption but also helps to lower the operating costs of the excavator.
- Efficient Hydraulic Circuit Design: The overall hydraulic circuit design of the pump is optimized to minimize energy losses. Through the use of advanced flow - control valves and pipelines with low - resistance characteristics, the pump can transfer hydraulic oil with minimal pressure drops, improving the overall energy efficiency of the hydraulic system.
3. Compatibility with LiuGong 950 - 970 Series Excavators
The MVP48.45 is perfectly compatible with LiuGong 950 - 970 series excavators. It is designed to integrate seamlessly into the existing hydraulic systems of these excavators. The connection ports, flange sizes, and mounting dimensions of the pump are precisely matched to those of the LiuGong excavators, ensuring easy installation and replacement. This compatibility also means that the pump can work in harmony with other components of the hydraulic system, such as the hydraulic cylinders, valves, and hoses, to achieve optimal performance.
4. Quality Assurance

After the pump is assembled, it is subjected to comprehensive performance tests, including pressure tests, flow rate tests, and durability tests. Only pumps that pass all these tests are qualified for sale.
5. After - sales Service
- Technical Support: Our professional technical support team is available to provide assistance at any time. Whether you have questions about the installation, operation, or maintenance of the pump, our technicians can offer detailed guidance and solutions. We can also provide on - site technical support if necessary, ensuring that your excavator can operate smoothly with the new pump.
- Spare Parts Supply: We have a complete spare - parts supply system to ensure the timely supply of spare parts for the MVP48.45. In case of any component failure during the operation of the pump, you can quickly obtain the required spare parts, minimizing the downtime of the excavator. Our spare - parts inventory is regularly updated to meet the needs of our customers.
6. Application Scenarios
The LiuGong 950 - 970 series excavators equipped with the MVP48.45 hydraulic axial piston pump are widely used in various construction projects.
- Building Construction: In building construction projects, the excavator can be used for foundation excavation, earth - moving, and material handling. The high - performance pump ensures that the excavator can work efficiently in different construction stages, such as digging deep foundations for high - rise buildings or moving large amounts of soil and construction materials on the construction site.
- Road Construction: For road construction projects, the excavator can be used for tasks like roadbed preparation, ditch digging, and slope shaping. The precise pressure control and high - flow rate of the pump enable the excavator to perform these tasks accurately and quickly, contributing to the smooth progress of road construction.
- Mining Operations: In mining operations, the excavator needs to work in harsh environments and handle heavy - duty tasks. The robust construction and high - performance characteristics of the MVP48.45 pump make it suitable for mining applications. It can provide the necessary power for the excavator to dig and load large amounts of minerals, ensuring the productivity and efficiency of mining operations.
In conclusion, the Excavator Hydraulic Axial Piston Pump MVP48.45 for LiuGong 950 - 970 is a reliable, high - performance hydraulic component. With its advanced features, excellent compatibility, strict quality assurance, and comprehensive after - sales service, it is an ideal choice for enhancing the performance and reliability of LiuGong 950 - 970 series excavators in various construction and mining applications.
