Priming unit for evacuation of centrifugal pumps pumping clean or slightly contaminated fluids and where dry running is admissible for short periods of time.

Level controlled priming systems for evacuation of centrifugal pumps pumping clean or slightly contaminated fluids. Due to the level-control, the system is also suitable for plants where gas- or air inclusions have to be separated effectively even during operation of the centrifugal pump.
