What are Positive Displacement Pumps designed to do?

Positive Displacement Pumps are specifically designed to collect fluid and convert the fluid's velocity into pressure. This process occurs as the pump traps a specific volume of fluid and then forces it out through a discharge outlet. The mechanism relies on the physical displacing of fluid, which allows for the generation of pressure as the fluid is moved.

These pumps operate based on a fixed volume, meaning that with each cycle, a consistent amount of fluid is moved. This characteristic makes Positive Displacement Pumps particularly useful in applications where precise control over flow rates and pressure is necessary, such as in firefighting systems where maintaining a certain pressure is critical for effective water delivery.

In contrast, the other answer choices do not accurately describe the function of a Positive Displacement Pump. They either misrepresent the purpose of the pump or limit its capability to specific scenarios, neglecting the comprehensive functionality of pressure conversion and fluid movement that these pumps are designed to perform.
