The main purpose of mechanical seals is to:

• A. Enhance pump efficiency
• B. Control water leakage from the stuffing box
• C. Reduce vibration
• D. Increase pressure

Answer: (B)

The main purpose of mechanical seals is to control water leakage from the stuffing box. Mechanical seals are designed to provide a reliable barrier between the pump's rotating shaft and the casing, preventing water and fluid from leaking out of the pump. This is critical in maintaining the efficiency and safety of the pump system, as leaks can lead to reduced efficiency, potential damage to the equipment, and environmental concerns. Mechanical seals achieve this by forming a tight seal that withstands the pressure and operating conditions within the pump. While the other options may relate to the functioning of pumps, they do not accurately define the primary role of mechanical seals. Enhancing pump efficiency is more a function of the overall pump design and operation. Reducing vibration is generally addressed by other components, such as mounts or dampeners. Increasing pressure is typically accomplished through the pump's design and configuration, not specifically through the use of mechanical seals.
