In hydraulic terminology, what term describes the instrument that supplies flow and pressure to the system?

• A. Pump
• B. Switch
• C. Sensor
• D. Gauge

Answer: (A)

In hydraulics, the device that supplies flow and pressure to the system is the pump. The pump is the energy source for the hydraulic circuit: it moves fluid from the reservoir into the system and creates the flow. As the fluid flows and encounters resistance from valves, cylinders, and other components, the pump develops the pressure needed to drive those loads. Other devices don’t provide both flow and pressure. A switch merely turns the system on or off; it doesn’t add energy or push fluid. A sensor measures a condition such as pressure or temperature, but it doesn’t generate flow. A gauge indicates pressure (or sometimes flow) but it only reads the system state, not supply energy.
