What is the purpose of a mechanical seal?

• A. Transmits input power from the driver to the impeller
• B. Increases the pressure of the liquid
• C. Prevents water leakage from the pump
• D. Supports the weight of the shaft assembly

Answer: (C)

A mechanical seal is specifically designed to prevent the leakage of water or other fluids from the pump. It creates a tight seal around the rotating shaft, which is crucial for maintaining the efficiency and functionality of the pump system. By ensuring that the fluid does not escape from the pump, mechanical seals help to conserve resources, protect the environment, and maintain the desired pressure and flow within the system. While transmitting input power from the driver to the impeller is a function of other components within the pump assembly, it is not the role of a mechanical seal. Similarly, increasing the pressure of the liquid is typically achieved through other means, such as the impeller's design and operation. Supporting the weight of the shaft assembly is handled by bearings, which are separate from the function of mechanical seals. Thus, the primary and most critical purpose of a mechanical seal remains to prevent water leakage, protecting the pump's efficiency and operational integrity.
