🔍 Key Concepts

• Centrifugal vs. positive displacement pumps – how they move liquid and how flow/pressure behave • Net positive suction head (NPSH) and what “positive suction” really means for pumps • Effect of pump speed (RPM) on flow rate and discharge pressure in centrifugal pumps

💭 Think About

• Ask yourself: Does a centrifugal pump trap and push fixed volumes of liquid each stroke/revolution, or does it impart velocity and convert that to pressure? • Consider what happens in practice: If you speed up a centrifugal pump (higher RPM) with the same suction conditions, what usually happens to the discharge pressure and flow? • Think about whether a centrifugal pump always requires liquid above the pump (flooded suction), or if it can operate with other suction arrangements when properly designed and primed.

✅ Before You Answer

• Verify the definition of a centrifugal pump versus a positive displacement pump in your engineering reference or license prep material. • Check how discharge pressure changes in a centrifugal pump when RPM increases (look at pump characteristic curves if you have them). • Confirm whether the phrase "must have a positive suction" is an absolute requirement for all centrifugal cargo pumps, or if this depends on installation and design.
