What is the primary function of the packing in the stuffing box of a centrifugal pump?

• A. Prevent vibration
• B. Prevent corrosion
• C. Prevent leakage of the fluid
• D. Improve efficiency

Answer: (C)

The primary function of the packing in the stuffing box of a centrifugal pump is to prevent the leakage of the fluid. The stuffing box is designed to seal the shaft that rotates within the pump, and the packing material is placed around the shaft to create a tight seal. This seal is essential because it prevents the fluid being pumped from leaking out of the pump around the shaft, which not only maintains efficiency but also protects against environmental contamination and loss of product. Proper sealing is crucial for operational safety and maintaining the integrity of the pump's function, as any leakage can lead to reduced performance and increased maintenance needs.
