Submersible pump are centrifugal pumps of simple construction, in which the motor wheel is placed in the elongated shaft of the engine. They are assembled right on the receptacle, and submerged along with the pump pipes in the cooling liquid.

Notice that the maximum cooling average level should be a few centimetres under the fixing flange.

the liquid flow indicated in the diagrams is to be used in 1mm2/s 20ºC.

As for the oil transport, the values decrease in connection with the viscosity and resistence of the piping, which increases.
