Tender text

Fully submersible, multistage pump for pumping industrial and drinking water (ACS rating) with radial or semi-axial impellers in sectional construction for vertical or horizontal installation, with built-in non-return valve. Corrosion-free, three-phase AC motor for direct or star-delta starting with water-glycol filling, alternatively with drinking water filling. Hermetically cast motor with enamel-insulated winding, resin-impregnated or rewindable with PVC-insulated winding, and self-lubricating bearings. The motor is cooled by the pumped fluid. Therefore, the unit must always be operated immersed. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. In cases of horizontal installation, a cooling jacket must always be provided .
