What is one of the key purposes of seal water in a pump?

• A. Prevent water hammer
• B. Cool and lubricate the packings
• C. Protect the impeller
• D. Lubricate the volute

Answer: (B)

One of the key purposes of seal water in a pump is to cool and lubricate the packings. In pumping systems, packing is used to create a seal around the rotating shaft and prevent leakage of the pumped fluid. This packing can generate significant heat due to friction as the pump operates. Seal water helps to dissipate this heat, preventing overheating which can lead to premature wear or failure of the packing material. Additionally, the seal water provides lubrication, reducing friction between the packing and the shaft. This further enhances the durability and effectiveness of the packing, ensuring a reliable seal while maintaining optimal pump performance. Overall, the role of seal water in cooling and lubricating the packings is essential for the proper functioning and longevity of the pump system.
