ISW series horizontal centrifugal water pump is a single-stage, single-suction horizontal centrifugal pumps, characterized by smooth operation, low noise and high concentricity of components. This product can be applied to convey seawater or light corrosive liquid and other liquids with physical properties similar to clear water, and can be applied to farmland irrigation, long-distance water supply, urban drainage and other fields. In addition, the motor of this pump adopts low-noise bearings, and the impeller adopts the best static and dynamic balance, so it can be used in the occasions where the noise environment requires strict requirements.
ISW series horizontal centrifugal pumps feature a unique structural design inspired by vertical pumps, with their design and manufacture strictly adhering to the international standard ISO 2858 and the national standard for pipeline centrifugal pumps, JB/T 53058-93. When the pump starts, the rotating impeller creates a low-pressure zone, drawing liquid into the pump casing under negative pressure. After entering the pump casing, the rotating impeller rapidly accelerates the liquid, generating pressure through centrifugal force, and ultimately propels the liquid into the centrifugal pump's discharge pipe.
