Конструкција
Submersible-motor pump for vertical or horizontal installation.
Hydraulics
Multistage submersible-motor pump with 4" NEMA connection and radial or semi-axial impellers with sectional construction. Integrated non-return valve. All parts in contact with the fluid are made of corrosion-free materials.
Motor
Corrosion-free three-phase AC motor for direct starting. Sealed and hermetically cast motor, resin-impregnated, with enamel-insulated winding, self-lubricating bearing, with water-glycol filling.
Cooling
The motor is cooled by the fluid. The motor must always be operated in submerged state. The limit values for the max. fluid temperature and the minimum flow rate must not be exceeded. Vertical installation is possible optionally with or without cooling jacket. Cooling jacket is required for horizontal installation.
