Construction

Submersible motor pump for vertical installation

Hydraulics

Multistage submersible motor pump with radial impellers with sectional construction and integrated non-return valve. All parts in contact with the fluid are made of corrosion-free materials.

Motor

Corrosion-free, oil-filled single-phase motor for direct starting, with self-lubricating bearing.

Cooling

The motor is cooled by the fluid. The motor must always be operated in submerged state. The limit values for the max. fluid temperature and the minimum flow rate must not be exceeded. Only vertical installation is possible.
