Centrifugal pump parts include

Centrifugal pump parts include

• A. diaphragm
• B. piston
• C. rotor
• D. volute

Answer: (D)

The main idea is recognizing the parts that form a centrifugal pump and how they work together. The volute is the pump casing that surrounds the impeller. It collects the high-velocity fluid discharged by the impeller and guides it toward the discharge outlet. As the fluid moves through the volute’s expanding cross-section, its velocity decreases while its pressure increases, converting kinetic energy into usable pressure for delivery. Diaphragms and pistons are characteristic of positive-displacement pumps, which use a flexible membrane or a moving piston to trap and move a fixed amount of fluid, not the energy-transfer method used in centrifugal pumps. The rotating component that actually imparts energy to the fluid is the impeller (often called rotor in some contexts), but it is the volute that is specifically the stationary casing around the impeller and a standard part of centrifugal pump design.
