    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: How do I choose a metering pump?

    Choosing a metering pump involves several critical considerations. Firstly, identify the required flow rate and pressure for your specific application. This will determine the pump's capacity. Next, select a pump type, such as diaphragm, piston, or peristaltic, based on the fluid's compatibility and the accuracy needed.

    Consider the chemical compatibility of pump materials with the fluid being pumped to ensure long-term reliability. Evaluate the working environment, as factors like temperature, pressure, and potential corrosive atmospheres can affect pump selection. Additionally, think about the required control and automation features for precise dosing.

    Factor in maintenance requirements, as some dosing pumps may need more frequent attention than others. Lastly, consider the cost of the pump, both upfront and long-term operational expenses. Weigh these factors to find a metering pump that meets your specific needs and budget. Consulting with a pump specialist may also be beneficial in making an informed decision.
