    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 the advantages of plunger dosing pumps?

    Plunger dosing pumps offer several advantages in various industrial applications. Firstly, they provide exceptional accuracy and precision in delivering precise volumes of liquids, making them ideal for applications where dosing accuracy is critical, such as water treatment or chemical processing. Their robust construction and design ensure reliability and durability, even when handling corrosive or abrasive fluids.

    Plunger metering pumps are known for their ability to generate high pressures, which is essential for applications that require the injection of chemicals or additives into systems with varying pressures. They can handle a wide range of viscosities, ensuring versatility in accommodating different fluids. Moreover, they have a low pulsation rate, reducing the likelihood of system wear and tear, and they are relatively easy to maintain.
