RCEV - Vertical chemical centrifugal pump in metal
The decision whether to use an open or closed impeller depends heavily on the type of the solids. The RCEV is used to convey mechanically contaminated, corrosive or neutral liquids such as phosphoric acid, highly contaminated sulphur, titanium dioxide slurries, copper dissolution acids as well as liquids that cannot tolerate localised heating by sliding bearings, e.g. concentrated ammonium nitrate solutions, DNT mixtures.
