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.
Fully automatic level-controlled compact priming system for the evacuation of single or several centrifugal pumps, especially in pump stations for the pumping of heavily contaminated pumping media such as e.g. untreated sewages, sludge, sinter water a.s.o.. Also used for the evacuation of siphon pipes.
Fully automatic central vacuum unit designed for level-controlled, permanent evacuation of several centrifugal pump units handling clean to lightly contaminated liquids. It is essential that the centrifugal pumps have to be evacuated operate on the same suction level.
Level-controlled gas discharge valve for automatic discharge of air or gas from siphon pipes via a pressure-controlled central vacuum unit, e.g. vatec-central vacuum unit type TDV.
Automatic vacuum system for central evacuation of several pump delivery side siphon pipes in water treatment or sewage plants. This set-up allows a friction start-up of the feed pump an prevents constriction of the pressure (hydraulic) main by automatically diverting the build-up of air or gas in the high point.
