PA10VO71DFLR/31R-VUC59N00 Axial Piston Fixed Displacement Pump A10VO A10VSO18/28/45/71/100/140/DR/DFR1/DFLR/DRS

3. Product features and advantages
Flexible variables: By adjusting the swing Angle of the swash plate, the flow rate can be infinitely variable, and the flow rate can be precisely provided according to the system requirements.
High pressure: The nominal pressure can reach 280bar, and the maximum pressure is 350bar, making it suitable for high-pressure hydraulic systems.
High efficiency: The volumetric efficiency is about 95%, and the total efficiency is about 90%, which can effectively reduce energy loss.
Low noise: With a reasonable design, the noise level during operation is relatively low, providing favorable conditions for the working environment.
Long service life: The main components are all under compressive stress, allowing the material strength performance to be fully utilized. Moreover, hydrostatic unloading is carried out on the rocket bearings, which enhances the service life of the bearings. The overall pump has high reliability and a long service life.
High power-to-weight ratio: It can provide a large power in a relatively small volume, has a good power-to-weight ratio, and is convenient for installation and use.

4. Usage functions and purposes
The main function is to convert mechanical energy into hydraulic energy, provide pressure oil for the hydraulic system, and precisely control the output flow and pressure according to the system’s requirements, achieving power transmission and control of the hydraulic system.
Application: Widely used in situations requiring high-pressure and high-flow hydraulic power, such as hydraulic systems in industrial automated production lines, metal processing equipment, construction machinery, etc.

5. Applicable machines and scenarios
Applicable machines: It is suitable for CNC machine tools, machining centers and other machine tool equipment, as well as hydraulic excavators, cranes and other construction machinery equipment. It can also be used in metallurgical equipment for processing and transporting materials such as steel and non-ferrous metals, as well as related equipment in processes such as oil extraction and chemical production.
Applicable scenarios: It performs exceptionally well in industrial production scenarios that require high-precision and high-efficiency hydraulic control, such as parts processing in automotive manufacturing, material handling and excavation operations in construction projects, etc.

7. Precautions for Use
Installation: It is recommended to use an elastic coupling to connect the pump and the motor. The coaxial Angle of the two shafts should be adjusted to ±0.1mm, and the angular error should not exceed 0.5 degrees.
Pipeline connection: The inner diameter of the oil drain pipe should be greater than φ12, and it should be ensured that the pressure inside the pump cavity remains below the normal pressure of 0.1MPa, and the impact pressure is less than 0.5MPa. If the pipe length is less than 1 meter, it should be installed separately and not converge with the return oil pipe. The end of the pipe should be immersed in oil. When steel pipes are used for the suction port or discharge port, to avoid noise caused by additional loads, it is recommended to use rubber hoses.
Hydraulic oil selection: The viscosity range of the oil is 20-400mm³/s when the operating temperature is 0-60° C. Clean petroleum-based hydraulic oil, such as hydraulic oil equivalent to ISO VG32 or 46.
Filter Settings: An oil tank filter with a diameter of at least 100μm must be installed at the oil suction port, and a pipeline filter with a diameter of less than 10μm must be installed in the circuit. The filter element of the filter should be inspected regularly, cleaned or replaced.
Start-up and operation: Before the first start-up, clean hydraulic oil should be injected into the pump through the oil filling port, approximately 700cm³, and the rotation direction of the pump should be checked to ensure that the adjusted pressure of the relief valve is basically in the unloaded state. During operation, closely monitor the condition of the pump, such as its sound and temperature rise.
