CLLa Series Marine Vertical Centrifugal Pump

Introduction:

CLLa series marine vertical centrifugal oumos can be used as marine ballast pump, CLLa series manne vertical centrifugal pumps ca bilge pump, fire pump, cooling pump and transport seawater,fresh water and other incorrosive liauids.The liauird temderature don't exceed 75℃.

If there is more silt and sand in the transported liquird.Then the liquid can be separated with the cyclone separator, separated clean liquid will be transported into the sealing chamber of the pump and sewage will enter the suction chamber of the pump.

If customers want to the pump in which the cyclone separator has been installed. The requirement must be noted in the explantion in the contract.

The typical example and its explanation for the pump type

For example : 125CLLal1-13A
125-entrance diameter of the pump,mm.
CLLa- marine vertical centrifugal pump
1-footnote.it expresses that the frequence of the driving motor of the pump is 60Hz.
13-approximate value of pump's specific speed devided by ten
A-a mark it expresses that the impeller van has been cut.

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 techriical performancy parameters are showed in table 2.
