DA series single-suction multistage centrifugal pumps are used to deliver clean water of non-corrosive medium similar to clean water in physical and chemical properties, with the volume of solid insoluble not exceeding 0.1％ of unit volume. Temperature of medium:-15℃～+120℃. DA pumps are used in mining and water supply of plant and cities.
DA型泵供输送温度在-15℃～+40℃之间的清水或物理、化学性质类似于清水的其他液体，若液体中含杂质，则杂质量不应超过0.1%。主要用于高层建筑供给生活、消防用水，也可用于工厂，城镇，企业供水以及低压锅炉循环用水。
