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.
