  • Why You should take this seminar

    Increase your understanding and knowledge of centrifugal pumps including their design, selection, operation and maintenance. Moreover, this centrifugal pumps seminar will aid you in increasing productivity and reducing costly downtime.

    It is important to understand what a pump is and how it works in order to solve problems. There are strong misconceptions about centrifugal  pumps. Instructors of your centrifugal pumps seminar will explain the basics so that you will be adequately prepared to understand certain design considerations, including sizing. In addition, this course provides the inside information on why and how centrifugal pumps are designed.

    Our 3-day (Regional Hub) version of this seminar includes hands-on lab exercises that demonstrate and reinforce the practical techniques of maintenance and troubleshooting.
