Centrifugal pumps circulate water and transfer liquids. They are commonly used in commercial and industrial applications, such as filtering water, boosting water pressure, and aerating ponds and fountains. Self-priming, portable utility pumps speed up drainage. Corrosion-resistant pumps move chemicals and resist damage from acids or chemicals. Booster pumps increase pressure in city mains or residential buildings and can maximize filtration operations in pond systems.
