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 specifically designed for LiuGong 950 - 970 excavators. It plays a crucial role in the hydraulic system of the excavator, providing the necessary hydraulic power to drive various working mechanisms, such as the boom, arm, bucket, and swing mechanism. This pump is a key element in ensuring the efficient and reliable operation of the excavator, enabling it to handle a wide range of construction tasks with precision and power.
2. Product Features
2.1 High - Quality Materials
- The pump is constructed using top - grade materials. The pump body is made of high - strength alloy steel, which offers excellent durability and resistance to wear and corrosion. This ensures that the pump can withstand the harsh working conditions of construction sites, where it may be exposed to dust, moisture, and high - pressure hydraulic fluids for extended periods.
- The pistons are crafted from a special alloy that has high fatigue resistance and low friction coefficient. This allows for smooth operation of the pump, reducing energy losses and minimizing the risk of component failure due to excessive wear.
2.2 Advanced Design
- The MVP48.45 features an axial piston design, which is known for its high efficiency and compact structure. The axial piston arrangement allows for a more direct transfer of force, resulting in a higher volumetric efficiency compared to other pump designs. This means that the pump can deliver a larger volume of hydraulic fluid per unit of time, increasing the productivity of the excavator.
- It has a variable displacement mechanism that enables the pump to adjust its output flow according to the actual needs of the hydraulic system. When the excavator is performing light - duty tasks, such as moving the bucket slowly, the pump can reduce its flow output to save energy. Conversely, during heavy - duty operations like digging deep into hard soil, the pump can increase its flow to provide the necessary power.
2.3 Precise Manufacturing
- The pump is manufactured with extreme precision. The internal components, such as the pistons, cylinders, and valve plates, are machined to tight tolerances. This ensures a perfect fit between the components, minimizing internal leakage and improving the overall performance of the pump.
- Advanced manufacturing techniques, such as computer - numerical - control (CNC) machining and precision grinding, are used to produce the pump. This results in a high - quality product that meets or exceeds industry standards.
3. Performance Specifications
3.1 Flow Rate
- The MVP48.45 has a maximum theoretical flow rate of [X] liters per minute at a rated speed. This high flow rate allows the excavator to perform tasks quickly and efficiently. For example, when extending the boom of the LiuGong 950 - 970 excavator, the high - flow pump can ensure that the boom moves smoothly and rapidly, reducing the cycle time of the excavation process.
- The variable displacement feature enables the pump to operate at different flow rates within a certain range, providing flexibility in various working conditions.
3.2 Pressure Rating
- It can withstand a maximum working pressure of [X] bar. This high - pressure rating makes the pump suitable for handling heavy - duty tasks in construction applications. Whether it's digging through tough rock or lifting heavy loads, the pump can maintain a stable pressure output to ensure the reliable operation of the excavator's hydraulic actuators.
- The pump also has a built - in pressure - relief valve that protects the hydraulic system from over - pressure situations. In case the pressure in the system exceeds the set limit, the relief valve will open, diverting the excess hydraulic fluid back to the tank to prevent damage to the pump and other components.
3.3 Efficiency
- The pump offers high overall efficiency, with a volumetric efficiency of over [X]% and a mechanical efficiency of [X]%. High efficiency means less energy consumption, which not only saves operating costs but also reduces the environmental impact of the excavator. It also contributes to the overall reliability of the hydraulic system by minimizing heat generation during operation.
4. Compatibility
The MVP48.45 is specifically designed to be fully compatible with LiuGong 950 - 970 excavators. It has the correct mounting dimensions, flange types, and shaft configurations to ensure a seamless installation. The hydraulic connections are also designed to match the existing hydraulic lines of these excavator models, making the replacement process simple and straightforward. This compatibility ensures that the pump can integrate perfectly into the excavator's hydraulic system, maximizing its performance and reliability.
5. Application Scenarios
5.1 Construction Sites
- In general construction projects, the LiuGong excavators equipped with the MVP48.45 pump are used for earthmoving, trenching, and foundation work. The high - flow and high - pressure capabilities of the pump enable the excavator to dig deep into the ground, break up hard soil or rock, and load the excavated materials into trucks efficiently.
- For building construction, the excavator can use the pump - driven hydraulic system to handle tasks such as demolishing old structures, excavating for basements, and moving construction materials around the site.
5.2 Mining Operations
- In small - to - medium - scale mining operations, the excavator with this pump can be used for extracting minerals from the earth. The high - pressure performance of the pump allows the excavator to break through the hard rock layers in the mine, while the variable - displacement feature ensures energy - efficient operation during different stages of the mining process.
5.3 Road Construction
- During road construction, the excavator can be used for tasks like grading the roadbed, digging ditches for drainage, and moving large amounts of soil and gravel. The precise control and high - power output provided by the MVP48.45 pump enable the excavator to perform these tasks with high accuracy and productivity.
6. Quality Assurance
6.1 12 - Month Warranty
- We offer a comprehensive 12 - month warranty for the Excavator Hydraulic Axial Piston Pump MVP48.45. During this period, if the pump experiences any quality - related issues due to manufacturing defects, we will provide free repair or replacement services.
- Our warranty policy covers all components of the pump, including the pump body, pistons, cylinders, valve plates, and seals. We have a professional after - sales service team that is ready to respond promptly to any customer inquiries or issues. Once a problem is reported, our team will conduct a thorough inspection to determine the cause of the failure. If it is within the warranty scope, we will take immediate action to resolve the problem, minimizing the downtime of the customer's equipment.
6.2 Quality Control
- Before leaving the factory, each MVP48.45 pump undergoes a series of strict quality control tests. These tests include performance testing, pressure - testing, and leakage testing.
- Performance testing is carried out to ensure that the pump meets the specified flow rate, pressure, and efficiency requirements. Pressure - testing is used to verify that the pump can withstand the maximum working pressure without any damage or leakage. Leakage testing is performed to check for any internal or external leakage in the pump. Only pumps that pass all these tests are approved for shipment, ensuring that our customers receive high - quality products.
7. Customer Support
