Hydraulics

Multistage submersible motor pump with radial or semi-axial impellers in cased design. Integrated check valve. All parts in contact with the medium are made of corrosion-resistant material.

Motor

Corrosion-resistant reversible AC motor or three-phase motor for direct start-up. Sealed by a mechanical seal with self-lubricating bearings, with oil filling.

Cooling

The motor is cooled by a pumped medium. The engine must only ever be operated submerged. The limit value for the maximum medium temperature must not be exceeded and the limit value for the minimum volume flow rate must not be exceeded. Vertical installation can be carried out with or without a cooling jacket as an option. For horizontal installation, a cooling jacket is required.
