Hydraulics

Multistage submersible motor pump with radial or semi-axial impellers in split casing design. Integral check valve. All parts in contact with pumped media are made of corrosion resistant material.

Electric motor

Corrosion-proof single-phase or three-phase direct start electric motor. The motor is encapsulated in a resin encapsulated motor, the windings are coated with an insulating coating, the bearings are self-lubricating and filled with a water/glycol mixture.

Cooling

Motor cooling is achieved by pumped fluid. The motor must only be operated in immersed state. Observe the maximum temperature limits for the fluids to be pumped. Vertical installation can be carried out with or without a cooling jacket - optionally. Horizontal mounting is done with a cooling jacket.
