Description/construction
Submersible pump for vertical or horizontal installation.

Hydraulics

Multistage submersible motor pump with radial impellers in close-coupled design. With integrated check valve. All parts in contact with pumped liquid are made of corrosion resistant materials.

Electric motor

Corrosion-proof single-phase electric motor, direct starter, rewindable, oil filled, with self-lubricating bearings.

Cooling

Motor is cooled by pumped liquid. 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.
