Introduction to Plunger Metering Pumps

Plunger metering pumps are precision instruments extensively utilized in industries where accurate fluid transport is crucial. Known for their ability to handle high-pressure applications, these pumps are integral to processes requiring precise fluid flow and dosing.

Principles of Operation

The operation of a plunger metering pump is based on the reciprocating motion of a plunger within a cylindrical chamber. As the plunger retracts, it creates a vacuum that draws fluid into the chamber. When the plunger extends, it displaces the fluid through the discharge valve, ensuring precise volume delivery.

Common Applications of Plunger Metering Pumps

Plunger metering pumps are valuable across various sectors, including chemical processing, pharmaceuticals, oil and gas, and water treatment. They are particularly suitable for applications requiring:

• High-pressure liquid handling (typically up to 5000 psi).
• Dosing of corrosive and abrasive fluids.
• Accurate measurement in continuous processes.
