🔍 Key Concepts

• NPSH (Net Positive Suction Head) requirements for centrifugal feed pumps • Effect of feedwater temperature on pump suction conditions • How vapor formation/cavitation can cause a pump to lose suction

💭 Think About

• Think about what happens to water inside the suction line and pump casing as its temperature increases. At what point can it start to flash to steam? • Which of these choices would most directly affect the pressure conditions at the pump suction, rather than just the boiler’s operation? • Does a low boiler water level or low steam demand necessarily change conditions at the pump suction the same way a temperature change does?

✅ Before You Answer

• Identify which option would most reduce available NPSH at the pump suction • Consider which condition promotes cavitation or vapor locking in the pump • Verify which factors (level, demand, hot or cold water) actually change the vapor pressure of the feedwater at the suction
