Water supply from boreholes with a minimum diameter of 4" and a maximum immersion depth of up to 200 metres. Municipal water supply, sprinkling and irrigation, pressure boosting, lowering of the ground water level, industrial applications.
Pumping of water without long-fibre and abrasive constituents within the limitations of the specified minimums and maximums.
Total-immersion, multistage submersible with radial or semi axial impellers in sectional construction. Pressure housing, jacket pipe, stage covering and strainer made of stainless steel. Build in no-return valve in the pump head. All parts in contact with the pumped fluid are made of corrosion-free materials.
Corrosion-free single-phase AC or three-phase motor with enammeled windings in hermatically cast stator for direct starting. Sealed cast stator, resin-saturated, self-lubricating bearings. Motor cooling is effected by the temperature and flow velocity of the pumped liquid outside of the motor.
Submersible motor deep well pump with built in non-return valve , protection class IP 68 for the entire pump; 1.5m or 2.5m long detatchable connection cable 4x1.5mm2 cable cross-section.
AC version EM including switchbox with capacitor, thermal motor protection and On/Off switch. Includes packaging in addition to installation and operating instructions.
