Submersible pump with ACS approval for vertical or horizontal installation.
Multistage submersible-motor pump with 6/8″-NEMA- or from 10″ and larger with standardised connection and semi-axial impellers in sectional construction. Integrated non-return valve. All parts that come in contact with the fluid are made of corrosion-free materials.
Three-phase motor for direct or star-delta start. Sealed, hermetically cast motor, resin-impregnated, with enamel-insulated winding or rewindable motor with PVC-insulated winding, self-lubricating bearing, with water-glycol filling. Motors of the NU 611, NU 8…, NU 9… series are also available in drinking water version (T version).
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.
The pressure shroud is used for the direct installation of the unit in the pipe network. Standard models are without mounted non-return valves. The maximum inlet pressure is 10 bar.
