Pumps and compressors are essential components in almost all industries in that they are required to meet system demands and operate reliably. Failure to meet these requirements can have significant production (and hence cost) impacts.

Keeping these machines running with least troubles and shutdown decreases the downtime of the whole system. Right machine selection appropriate to the right application, right machine operation, effective maintenance programs, reliable monitoring system, and skilled personnel capable of doing the right trouble shooting are essential requirements for prolong machine life. All the above can be achieved via deeper understanding of the machines construction and tolerances, the limits and constrains on their operation, and the more effective controlling methods.


By attending this course you will gain an understanding of the characteristics of various types of Reciprocating Rotary pumps and compressors and their components. The course will provide engineers and technicians with information for the optimal selection, operation and maintenance of positive displacement pumps as well as positive displacement and dynamic compressors.
