    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: Is a metering pump a centrifugal pump?

    No, a metering pump is not a centrifugal pump. These two types of pumps serve different purposes and operate on distinct principles.

    A dosing pump is a type of positive displacement pump designed for precise and controlled fluid dosing. It delivers a highly accurate and consistent flow of liquid by displacing a fixed amount of fluid with each stroke or rotation, making it suitable for applications where precise dosing is critical, such as in chemical processing and water treatment.

    On the other hand, a centrifugal pump is a dynamic pump that uses a rotating impeller to create a flow of fluid by imparting kinetic energy to the liquid. It is commonly used for applications where a high flow rate is required, like moving large volumes of water in irrigation, HVAC systems, or industrial processes.
