Overview

Positive displacement pumps are designed to move fluid by trapping a fixed amount and forcing (displacing) that trapped volume into the discharge pipe. They are commonly used in applications requiring precise flow control, high pressures, or handling of viscous fluids. These pumps are essential in industries like oil and gas, chemical processing, and food and beverage production.
