Selection of Centrifugal Pumps, Operating Pump Systems

You are familiar with the functions of centrifugal pumps (mostly for liquids without solids) and you are able to select them optimally. You are able to access their operating characteristics in pump systems and to a certain extent, you are also familar with their operation limits.

Measuring methods to find correct technical pump data and useful hints to avoid measuring errors are also well known to you.
