YB4 Series Multipurpose Hydraulic Vane Pump With Medium And Low Pressure

As a professional hydraulic vane pump manufacturer, we are proud to introduce YB4 63-125mL/r 20kg medium and low-pressure hydraulic vane pump, which is a product with performance and wide application.
One of the main features of the YB4 hydraulic vane pump is its low-pressure capability. Our design team has carefully developed and optimized the pump to ensure stable performance in medium and low-pressure hydraulic systems. Whether in industrial manufacturing, logistics equipment, or agricultural applications, the pump can operate stably and provide equipment with the long-lasting, reliable, and efficient low- and medium-pressure hydraulic power required.
The YB4 pump has a lightweight weight (only 20kg), which makes it ideal for equipment that requires flexible movement and installation. Whether indoors or outdoors, the pump's lightweight design provides easy installation and operation, reducing the workload of equipment installation and maintenance.
Our YB4 hydraulic vane pumps also offer exceptional reliability and durability. We select high-quality materials and use advanced manufacturing technology to ensure long life and high reliability of our products. The pump can operate normally in various harsh working environments and working conditions, while providing stable performance and continuous working time, providing customers with reliable power support.
In terms of application, YB4 hydraulic vane pumps are widely used in various industries, such as construction engineering, petrochemical industry, metallurgy and steel, agricultural machinery, etc. Whether it is used to drive hydraulic systems, hydraulic machinery or provide power to engineering equipment, YB4 vane pumps are competent and meet customer needs.
YB4 63-125mL/r 20kg medium and low pressure hydraulic vane pump is a product with superior performance, reliability, and durability, suitable for a wide range of applications. We are committed to providing customers with the highest quality products and services to meet their various needs.

  • Precautions
    Install and use
    1. During installation, the coaxiality error between the pump shaft and the drive motor shaft should be ≤0.10mm and a flexible coupling should be used. The support structure should be firm, rigid, and able to fully absorb vibration. The pump shaft should be installed horizontally.
    2. Match the pipelines according to the size of the oil port, especially the oil inlet pipe, and install a safety relief valve in the system; the oil inlet pipeline must be strictly sealed to prevent air leakage, and the oil return pipe opening should be lower than the liquid level.
    3. Before starting the pump, check whether the inlet and outlet routes and the direction of rotation are correct. When the pump is newly installed or restarted after being stopped for a long time, the air should be released from the oil outlet. When starting, run at low pressure (1.5MPa).
    4. When the pump is installed higher than the oil level of the tank, the oil suction height is ≤500mm. It is best to keep the oil suction port lower than the oil level in the fuel tank. The positive pressure at the suction port should be ≤0.03MPa.
    5. Keep the oil clean, and the pipes and fuel tank must be thoroughly cleaned. Install a filter with sufficient capacity at a position above 50mm from the pump suction inlet to the bottom of the tank. The recommended accuracy is 100μm. A fine filter should be installed in the system, it is recommended to be 25μm and the oil cleanliness level should be within NAS12.
    6. The operating temperature of the oil should be controlled within the range of 15~55°C. When starting in severe cold and low temperatures, the oil should be heated, and the oil pump should be inched several times without load before running continuously without load.
    7. Pay attention to the viscosity and quality of the oil. It is recommended to use 32 anti-wear hydraulic oil when the ambient temperature is low.
    8. If you need to change the direction of the oil port, first remove the relevant pump body screws, be careful not to separate the left and right pump bodies, ensure that the heart piece rotates at a certain angle with the oil inlet, and then gradually tighten diagonally.
    9. After the entire pump is installed, rotate the pump shaft by hand. It should be even and flexible.
