CDSL marine electrical vertical reciprocating pump, CDSW marine electrical horizontal reciprocating pump,It is suitableto transport the sea water, the fresh water, the petroleum and the petroleum product in the ships, or transports other liquids which its physics, the chemical property are similar.

Or the temperature of the transported medium to be divided into the three ranks of high, middle and low .

（1） H - High temperature pump      ≯220℃     heavy diesel oil, heavy oil class

          The viscosity is smaller than5.86×10㎡/s        

（2） M - Middle temperature pump   ≯110℃     heavy diesel oil, heavy oil class

      The viscosity is smaller than 5.86×10㎡/s

（3） L - low temperature pump       ≯85℃      Light diesel oil, gasoline, sea water or fresh water

The viscosity is smaller than 5.86×10㎡/s

The marine electrical reciprocating pump defers to GB11034-89 strictly to produce.
