What is plunger pump?

A plunger pump is a type of positive displacement pump that uses a plunger or piston to move fluid through a cylinder. As the plunger moves back and forth, it creates a vacuum that draws fluid in during the suction stroke and then expels it under pressure during the discharge stroke. Plunger pumps are known for their ability to handle high pressures and are often used in applications such as hydraulic systems, oil and gas extraction, and water treatment. Their design allows for precise control of flow rates and is effective for viscous or abrasive fluids.
