Submersible pump for boosting and transportation of water from a borehole. Integrated non-return valve. Delivered with installed cable and wire. Incl. Capacitor box for one phase. Drinking water approved, RISE Type approval SC0323-18| 2019-03-07

Fully submersible, multistage pump for pumping industrial and drinking water with radial or semi-axial impellers in sectional construction for vertical or horizontal installation, with integrated non-return valve. Corrosion-free single-phase or three-phase AC motor for direct starting with water-glycol filling. Hermetically cast with enamel-insulated windings, resin-impregnated and self-lubricating bearings. The motor is cooled by the pumped fluid. Therefore, the unit must always be immersed for operation. 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.

Scope of delivery:

Submersible pump with connection cable and drinking water rating, RISE Type approval SC0323-18| 2019-03-07

Single-phase version including switchbox with capacitor, thermal motor protection and On/Off switch
