Submersible pump with ACS approval 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 that come in contact with the fluid are made of corrosion-free materials.
Motor
Corrosion-free single-phase or three-phase 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 pumped fluid. The motor must always be immersed when operated. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. Horizontal installation must be performed in conjunction with a cooling jacket.
Pressure shroud
The pressure shroud is used for the direct installation of the unit in the pipe system. Standard models are without mounted non-return valves. The maximum inlet pressure is 10 bar.
