The submersible pump is based on multi-stage
and centrifugal design.
All parts in contact with the flow medium are of
corrosion-resistant material.
The electric motor is protected of the hydraulic
part pump by two mechanicals seal and a oil
chamber for maintained the tightness of the
motor.
The pumps are supplied with a carrying rope.
The pump base contains a suction strainer.
The SE type model are fitted with a suction sup-
port to allow the connection of floating or fixed
suction filters, with 4 vibration absorbers for
