Describe the different types of centrifugal pump and their characteristics.
Identify the components of a centrifugal pump; describe the various types of impellers and casings; explain how packing helps to control leakage; and describe the operation, advantages, and components of mechanical seals.
Identify factors that affect pump capacity, recall variations of head, and describe factors that cause cavitation. also define NPSH and explain its significance in centrifugal pump operations and interpret the various types of pump performance curves.
Describe the steps involved in disassembling centrifugal pumps, identify the tests performed on centrifugal pumps during inspection, and describe the steps involved in reassembling centrifugal pumps.
Recall the preliminary requirements for overhauling horizontal centrifugal pumps, recall the procedure for disassembling and reassembling horizontal centrifugal pumps, identify the defective parts while performing tests during inspection, and recall the key points when working with horizontal multistage centrifugal pumps.
Recall the preliminary requirements for overhauling of vertical centrifugal pumps, recall the procedure for disassembling and reassembling vertical centrifugal pumps, identify the defective parts while performing tests during inspection, and recall the key points when working with vertical multi-stage centrifugal pumps.
