🔍 Key Concepts

• Mechanical seal construction on centrifugal pumps (rotating vs stationary faces) • Properties of common seal face materials in water service (soft/self-lubricating vs metallic) • Why dynamic seal surfaces must handle friction, wear, and slight misalignment

💭 Think About

• Think about which material would best tolerate continuous sliding contact with minimal lubrication from water alone. • Which option would reduce scoring and galling if two surfaces are rubbing together at pump shaft speed? • Among the choices, which material is commonly used as a seal face because it is soft, self-lubricating, and can run against a harder mating surface?

✅ Before You Answer

• Identify that the dynamic seal is the part that is in continuous relative motion, not the stationary housing. • Eliminate materials that are primarily structural metals and more likely to gall or corrode in sliding contact in water service. • Confirm which listed material is well known in industry as a common mechanical seal face for water pumps.
