What does a pump primarily create in the fluid?

• A. Volume
• B. Flow
• C. Pressure
• D. Temperature

Answer: (B)

A pump’s main job is to move fluid, injecting energy to push it through the circuit. The primary thing it produces is a volumetric flow—the rate at which fluid moves past a point. Pressure arises as a consequence of the resistance the fluid meets in the system (valves, restrictions, losses in hoses and components). So the pump creates flow, and the system’s pressure is what develops in response to that flow encountering load. Temperature isn’t a primary outcome of pumping in normal operation.
