CL Series Marine Vertical Centrifugal Pumps

Introduction:

CL series marine vertical centrifugal pumps are suitable to be ballast pump, bilge pump, cooling pump and fire pump. They can transport seawater, fresh water and other incorrosive liquids.The medium temperature don’t exceed 70℃.

The typical example and its explanation for the pump type

For example：50CL-30
50-entrance diameter of the pump,mm
CL- marine vertical centrifugal pump.
30-head of the pump,m

Main technical performance parameters of the pump

When the frequency of the driving motor is 50Hz, the main technical performancy parameters are showed in table l. And When the frequency of the driving motor is 60Hz, the main technical performancy parameters are showed in table 2.
