Description/construction

Submersible pump for vertical or horizontal installation.

Hydraulic part

Multistage submersible motor pump with radial impellers in split casing design. Integral check valve. All parts in contact with pumped liquid are made of corrosion resistant materials.

Electric motor

Corrosion-proof single-phase direct start motor. The motor is encapsulated in resin, the windings are lacquered and self-lubricating, the bearings are filled with a water/glycol mixture.

Cooling

Electric motor is cooled by pumped fluid. The motor must only be operated in immersed state. The maximum temperature limits for the pumped liquid and the minimum flow speed must be observed. Vertical installation can be carried out with or without a cooling jacket - at the customer's choice. Horizontal installation is done with a cooling jacket.
