Suction Lift Pump corresponds to which type?

• A. Submersible Pump
• B. Jet Pump
• C. Centrifugal Pump
• D. Diaphragm Pump

Answer: (A)

Suction lift describes pulling water from a source that is below the pump by creating a vacuum at the inlet. A submersible pump is designed to operate while completely submerged in the water source, so it sits below the surface and can draw water in without needing priming or relying on atmospheric pressure. Once energized, it pushes the water up through the discharge line, which is why this type is naturally associated with suction-lift situations. Other pump types listed are typically surface-mounted and rely on suction created at the intake or have different operating principles, so they’re not the typical match for suction-lift setups.
