Close-coupled self-priming centrifugal pumps are designed for continuous low-pressure circulation and transfer of non-flammable liquids, water circulation, irrigation, spraying and other general-purpose pumping applications. It is compatible with pump component materials where suction lift is required. Self priming centrifugal pumps are close-coupled to continuous duty motors and designed to provide high volume service for industrial and commercial applications such as process applications, for nonflammable liquids compatible with pump component materials, liquid and chemical transfer, dewatering, irrigation and decorative water features.
