The course covers centrifugal pumps and pump theory including how to read a pump curve and select the proper pump for the job. Several different ANSI end suction pumps are disassembled, checked, and reassembled to industrial standards. Three types of sealing are available: expeller, packing, and mechanical seal. The attendee performs accurate measurement of bearing shaft fits, precision setting of the impeller, checking for shaft straightness, packing installation as well as setting of a mechanical seal. Use of premade as well as “home made” gaskets are covered in the course. A pre-test is used to assess skill level at the beginning of the course and post-test is used involving actual pump rebuilding to document the level of improvement of the attendee. The attendee should be able to rebuild centrifugal pumps to factory standards.
