MILL 124 - Pump Repair

3 Credits
This course is designed to prepare the millwright to remove, disassemble, and reassemble centrifugal pumps. The course will start with an introduction of centrifugal pump history and part nomenclature. Compression packing and mechanical seals will be discussed, including how to remove, inspected and install them. The course will cover precision tool usage and set-up during the pump disassembly, inspection and reassembly processes. Pump performance will be covered focusing on the relationship between flow and pressure, and the causes and effects of pump cavitation. Students will learn conduct as-found checks and follow safety, removal, disassembly, and reassembly procedures.
