Personal Study : 5 hours

The objective in presenting this unit is to provide students with an in-depth knowledge and comprehension of pump, seal, and compressor construction, design applications, operations, selection, installation, and maintenance related issues.

 

The subject matter covered in this unit will include pump characteristics and operation, and the working principles and performance characteristics of reciprocating and centrifugal compressors. The basic principles and mechanics of seal operation will also be examined, including seal classification, design, and materials – ranging from elastomeric materials to cemented carbides. Students will also be instructed on the selection of the correct seal type, analyse failed seals and determine the cause/s of failure, learn how seal life can be extended and how premature seal failure can be reduced through simple modifications.

 

At the conclusion of this unit, students will have been imparted with the requisite knowledge to judiciously select, install, test and maintain pumps; comprehend the principles and mechanics of operation of reciprocating and centrifugal compressors; and, have considerable insights into all aspects of seals.
