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.

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

Priming unit for evacuation of centrifugal pumps pumping clean or slightly contaminated fluids. The unit is designed for those centrifugal pumps, which mainly operate under intake pressure condition and where re-evacuation is only required to a very slight degree.
