Automatic aspirator designed for centrifugal pumps where dry running is admissible for short periods of time.

Pressure controlled priming unit for evacuation of centrifugal pumps used in hazardous explosive area, e.g. on board ships. Re-evacuation after break of pump delivery during pump operation.

Automatic aspirator designed for the priming of centrifugal pumps where dry running is not admissible.

Pressure controlled priming unit for evacuation of centrifugal pumps used in hazardous explosive area, e.g. on board ships. Pump start signal when pre-evacuation is completed. Re- evacuation after break of pump delivery during pump operation.

Level controlled automatic priming unit for pre- and re-evacuation of individual or several centrifugal pumps.

Level controlled priming unit for effective pre- and re-evacuation of centrifugal pumps used in hazardous explosive area, e.g. on board ships. Pump start signal when pre-evacuation is completed. Effective re-evacuation due to separate installation in front of the centrifugal pump and level controlled evacuation independent from pump discharge pressure.

Level controlled automatic priming unit for pre- and re-evacuation of individual or several centrifugal pumps.

Level controlled priming unit for effective pre- and re-evacuation of centrifugal pumps used in hazardous explosive area, e.g. on board ships. Pump start signal when pre- evacuation is completed. Effective re-evacuation due to separate installation in front of the centrifugal pump and level controlled evacuation independent from pump discharge pressure.

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.
