Technical data
Tender text

Fully submersible, multistage submersible pump with radial impellers in sectional construction for vertical or horizontal installation, with built-in non-return valve.

Corrosion-free permanent magnet motor for direct starting for connection to the supplied frequency converter. Oil-filled motor with self-lubricating bearings, designed for high speeds up to 8400 rpm.

Operation with the frequency converter means the rotation speed of the unit is adapted to the current water requirements automatically. As a result, the submersible pump always delivers a constant pressure. 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 cooling, the frequency converter must be installed directly in the pipe outside the fluid (overflow-proof). For pumping water out of boreholes with a maximum immersion depth of 150 m and a max. sand content of 50 g/m³.
