This course provides a comprehensive understanding of the various types of reciprocating, rotary, and centrifugal pumps. This includes piston pumps, plunger pumps, rotary pumps, screw pumps, two- and three-lobe pumps, cam pumps, vane pumps, bellows-type metering pumps, diaphragm pumps, canned motor pumps, and centrifugal pumps. The characteristics, selection criteria, sizing calculations, sealing arrangements, common problems, repair techniques, as well as the preventive and predictive maintenance of these pumps are covered in detail.

This course will provide the candidates with a complete and up-to-date knowledge of pumps and their systems. Further, participants will learn more about selection, operation and maintenance strategies which will assist in increasing pump availability and reliability. Upon the completion of this program, the candidates will be able to troubleshoot all types of pump problems. The course will introduce the candidates to the different types of pumps and their associated terminology. Centrifugal and positive displacement pumps, packing, mechanical seals and sealing systems, bearings and couplings will all be discussed. The application of the different types of pumps will be discussed along with their suitability for different operational duties. Pump operation, troubleshooting and maintenance will be dealt with in depth.
