🔍 Key Concepts

• Centrifugal pump performance when driven at constant speed • Difference between internal wear-related losses and suction conditions (NPSH / cavitation) • How mechanical alignment/packing issues vs. hydraulic clearances affect flow rate

💭 Think About

• Ask yourself: Which option would most directly reduce the pump’s ability to develop head and maintain flow at the same speed? • Which condition would typically cause internal recirculation or leakage inside the pump rather than change the suction pressure condition? • Which choices describe conditions that would actually improve suction conditions instead of hurting flow at the design speed?

✅ Before You Answer

• Identify which options would improve NPSH available and therefore are unlikely to reduce flow at constant speed. • Consider which component, if damaged or excessively worn, would increase internal bypass/leakage from high-pressure to low-pressure side inside the pump. • Check your pump theory: for a centrifugal pump on its curve at constant speed, what changes will shift operating point to lower flow without changing speed?
