Standard Chemical Dosing System

Dosing Pump System Application Guide
  • 1. Y Strainer

    ‌Y Strainer‌: Mainly be used to filter impurities in the medium, protect the normal use of metering pumps and valve equipment, and ensure the smooth operation of the entire pipeline system.

  • 2. Flow calibration Column

    ‌Flow calibration column‌: Mainly be used to accurately calibrate and detect the output flow of the metering pump, ensuring the working accuracy and reliability of the pump, and making it easy for users to observe the flow situation.

  • 3. Pressure Gauge

    Pressure gauge: Mainly be used to monitor the operation of the working medium in pressure vessels or pipelines and provide operators with reliable pressure parameters to control the production process and ensure product quality and equipment safety.

  • 4. Safety Relief Valve

    Safety relief valve‌: Mainly be used to protect the safety of the system, stabilize the hydraulic chamber pressure through automatic opening and closing and prevent accidents due to excessive pressure, while ensuring that it can be accurately adjusted to adapt to different working pressure requirements.

  • 5. Flow Meter

    Flow meter: Mainly be use to accurately measure fluid flow through the variable area measurement principle, while adapting to a variety of media and harsh environments, providing intuitive and easy-to-read flow data to ensure the accuracy and reliability of the measurement process.

  • 6. Pulsation Dampener

    Pulsation Dampener‌: Mainly be used to eliminate pressure and flow pulsations in the pipeline caused by the movement of the pump body, protect downstream equipment, improve system stability and efficiency, and extend the life of the pump and system equipment.

  • 7. Back Pressure valve

    Back pressure valve‌: Mainly be used to ensures the stable operation and metering accuracy of the system by maintaining constant pressure, preventing liquid backflow, providing safety protection, reducing water hammer impact and improving the working environment.
