Water Ring Vacuum Pump by AB-VAK PUMPS & ENGINEERING CO

Water Ring Vacuum Pump are rotary pumps using water as sealing fluid. It basically consists of cylindrical casing with control dies on either sides. Inside this consists an eccentrically lo­cated impeller with curved blades. The liquid introduced is set into rotary motion by the impeller forming a water ring concentric with casing. Cells formed between the blades and the ring vary in volume from maximum to minimum with each revolution. The suction medium enters this space through the opening in control disc & are then compressed out through the exhaust pipe along with the sealing liquid.

Installation as a compressor: Water-ring Compressors are equipped on the pressure side with a water separator in which the ring-water is separated from the compressed air. This is fitted with a float valve which allows the water to escape. It is possible to re-circulate this water with a closed system, similar to that for a vaccum pump, The non-return valve for a Water-ring Compressor is to be fit-
ted to the pressure piping. The working pressure is limited by fitting a safety
