    Plunger Dosing Pump Working Principle

    Through the reciprocating motion of the plunger, the working medium is directly sucked in or discharged. Since both the plunger and seal are in direct contact with the medium, choosing a jointly made plunger material and seal form can ensure that the pump has more ideal performance during operation.

    Tips: What are metering pumps very sensitive to?

    Metering pumps are very sensitive to various factors due to their precise and controlled dispensing of fluids in a wide range of applications. Some key sensitivities include:

    • Flow Rate Accuracy: Dosing pumps are highly sensitive to maintaining consistent flow rates, making them critical in applications where precise dosing is essential, such as chemical manufacturing and water treatment.
    • Pressure Variations: Fluctuations in system pressure can impact the accuracy of metering pumps, requiring specialized designs to maintain steady output.
    • Viscosity Changes: Changes in fluid viscosity can affect the pump's ability to dispense accurately, necessitating adjustments or specialized pumps for handling different viscosities.
    • Chemical Compatibility: The materials used in metering pumps must be compatible with the fluid being pumped to avoid corrosion or damage, making chemical compatibility crucial.
    • Temperature: Extreme temperatures can affect pump performance and may require additional temperature control measures.
    • Maintenance and Calibration: Regular maintenance and calibration are critical to ensure the continued accuracy and reliability of metering pumps.

    Dosing pumps are highly sensitive to flow rate, pressure, viscosity, chemical compatibility, temperature, and maintenance, making them indispensable for applications requiring precise fluid dosing.
