          CWZ Series Marine Horizontal Self-Primimg Centrifugal Pumps

          CWZ Series Marine Horizontal Self-Primimg Centrifugal Pumps

          Introduction:

          CWZ series marine horizontal self-primimg centrifugal pumps are suitable to be ballast pump, bilge pump, cooling pump and fire pump. lt can transport seawater,fresh water and other incorrosive liquids.The medium temperature don't exceed 75℃.

          The typical example and its explanation for the pump type

          For example:32CW2-5
          32-entrance diameter of the pump,mm
          CWZ- marine horizontal self-primimg centrifugal pump
          5-approximate value of pump's specific speed devided by ten

          Characteristics parameters

          If voltage is 440V, frequency is 60Hz, then footnote "1" added behindCWZ,as 32CWZ1一5.
