True Vacc Water-ring vacuum pumps are rotary pumps using water as sealing fluid.  It basically consists of cylindrical casing with control disc on either sides.  Inside this consists an eccentrically located balanced impeller with curved blades.  The liquid introduced is set into rotary motion by 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 alongwith the sealing liquid.
