Which pump type has the suction inlet located on the side opposite the stuffing box and with the nozzle facing perpendicular to the shaft?

• A. End Suction Pump
• B. Horizontal Pump
• C. Fire Pump
• D. Gear Pump

Answer: (A)

End suction pumps are designed so the suction connection is on the end opposite the stuffing box, and the discharge nozzle points perpendicular to the shaft. Fluid enters axially through the suction path, flows into the impeller, and is expelled radially through a discharge nozzle that runs at 90 degrees to the shaft. The stuffing box houses the shaft seal and is located on the opposite side from the suction inlet, which is exactly what this description describes. This configuration is a defining feature of end suction pumps, distinguishing them from other pump types where the suction and discharge orientations are not specified in that way.
