INTRODUCTION

Assuming that a plant is a body of human being, pumps are the "heart" of the body. Those play very important and vital roles to flow the "blood" of a plant. In every plant or production operation system, we find pumps. However, unlike bolts and nuts, neither industry nor production-operation management will put pumps in stock. It is NOT cost effective and is very uncommon practice to put a complete set of pump in the warehouse stock due to financial reasons.

Therefore, properly specifying, selecting, installing, operating and maintaining pumps are very significant and are very important steps to have "trouble free" during the entire life of the plant operation. Thus, proper maintenance and operation is also the key to reduce the entire cost of the plant and production operation system.

This five-day training will provide a comprehensive knowledge and understanding of pump selection, installation, operation, and maintenance program. The training will concentrate in centrifugal pump as they are the most common one used in the industries and day life.
