    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: Difference between plunger and diaphragm dosing pump

    Plunger and diaphragm dosing pumps are both types of positive displacement pumps used for precise chemical injection in various industries. The key difference lies in their pumping mechanisms.

    Plunger Dosing Pump: Plunger metering pumps use a reciprocating plunger or piston to displace the fluid. Fluid is pushed through a system of valves, usually ball or check valves, to achieve accurate dosing. Plunger pumps are known for high-pressure capabilities and are suitable for applications requiring consistent and precise dosing.

    Diaphragm Dosing Pump: Diaphragm metering pumps utilize a flexible diaphragm that moves back and forth to displace the liquid. The diaphragm isolates the pumped fluid from the moving parts, making it suitable for corrosive or abrasive chemicals. Diaphragm metering pumps are favored for their ability to handle a wide range of chemicals and maintain excellent leak-tightness.

    All in all, plunger dosing pumps excel in high-pressure applications, while diaphragm dosing pumps offer versatility and chemical compatibility, making them more suitable for corrosive or abrasive substances.
