Which part of a pump houses the packing or mechanical seal?

• A. The impeller
• B. The stuffing box
• C. The discharge pipe
• D. The inlet valve

Answer: (B)

The packing or mechanical seal of a pump is located in the stuffing box. The stuffing box is specifically designed to contain the packing material that helps prevent leakage of the pumped fluid around the shaft where it exits the pump casing. This is crucial because it ensures that any liquid being pumped does not escape and that pressure is maintained within the system. The design of the stuffing box allows for adjustments to be made to the packing material, ensuring an effective seal throughout the operational lifespan of the pump. The other components mentioned serve different functions: the impeller is responsible for moving the fluid within the pump, the discharge pipe carries the fluid away from the pump, and the inlet valve controls the flow of fluid into the pump. Each of these parts is vital for the overall operation of the pump, but none of them are involved in containing or managing the packing or mechanical seal, which is the primary function of the stuffing box.
