Q

A centrifugal pump designed to handle a liquid with a temperature of 250°F or greater must be provided with __________.

🔍 Key Concepts

• High-temperature centrifugal pump design and how temperature affects seals and packing • Differences between mechanical seals, packing, and seal/flush lines • Why preventing vaporization/flash and seal damage is critical at temperatures ≥ 250°F

💭 Think About

• Which option directly addresses what happens to the liquid and the seal area when temperature is very high? • Think about how you keep the seal area of a pump cool, lubricated, and under enough pressure to prevent flashing at 250°F. • Which device or feature is commonly used to route a small flow of liquid to the seal or stuffing box area for cooling and sealing?

✅ Before You Answer

• Verify which choice provides continuous cooled/clean liquid to the seal or stuffing box area. • Check which options are types of seals/packing versus something that supplies liquid to them. • Confirm which feature is specifically recommended when pumping liquids at 250°F or above to prevent flashing and seal failure.
