Fully submersible, multistage submersible pump with radial impellers in sectional construction for vertical or horizontal installation, with built-in non-return valve. Corrosion-free asynchronous motor with integrated frequency converter with a fixed speed of up to 8400 rpm for connection directly to the alternating current system. Rewindable oil-filled motor with self-lubricating bearings, designed for high speeds. The motor and the frequency converter are cooled by the fluid. Therefore, the unit must always be operated immersed. In cases of vertical installation, a cooling jacket must be provided depending on the diameter of the bore. In cases of horizontal installation, a cooling jacket must always be provided . For pumping water out of boreholes with a maximum immersion depth of 150 m and a max. sand content of 50 g/m³.
