What is a primary function of a stuffing box in pump operations?

• A. Reduce pump weight
• B. Minimize fluid contamination
• C. Prevent leakage of fluids
• D. Enhance pumping speed

Answer: (C)

A stuffing box is a critical component in pump operations, primarily designed to prevent leakage of fluids. It achieves this by enclosing the shaft that rotates through the pump casing, providing a seal that minimizes the escape of liquid from the pump while also protecting the shaft from the fluid. The packing material within the stuffing box compresses against the shaft as it rotates, creating a tight seal that reduces the chance of leaks. While minimizing fluid contamination is an important aspect of pump operation, preventing leakage is the primary function of the stuffing box. Other options, such as reducing pump weight or enhancing pumping speed, are not functions associated with the stuffing box's design or operation. These aspects might influence overall efficiency or performance in different ways but are not directly related to the primary function of the stuffing box.
