What is dry ice primarily used for in a pump shop?

• A. To cool liquids quickly
• B. To freeze pump wear rings to ease installation
• C. To clean equipment surfaces
• D. To enhance lubrication of components

Answer: (B)

Dry ice, which is solid carbon dioxide, is primarily used in a pump shop for the purpose of freezing pump wear rings to ease installation. When dry ice is applied to the wear rings, it causes them to contract slightly due to the extreme cold, making it easier to install them onto the pump components. This technique helps in achieving a proper fit without damaging the components, ensuring that they can operate effectively once installed. In contrast, other common uses of dry ice, like cooling liquids quickly or cleaning equipment surfaces, are not as directly applicable to pump shop operations, where the focus is on assembly and maintenance of mechanical systems. Additionally, enhancing lubrication of components is not a function of dry ice; lubrication typically involves oils or greases that reduce friction and wear in mechanical systems rather than utilizing temperature changes from substances like dry ice.
