Descrição/construção

Submersible-motor pump for vertical or horizontal installation.

Hydraulics

Multistage submersible-motor pump with radial or semi-axial impellers in jacket design. Integrated non-return valve. All parts in contact with the fluid are made of corrosion-free materials.

Motor

Rewindable, corrosion-free single-phase or three-phase motor for direct starting.Sealed by mechanical seal with self-lubricating bearings, with oil filling.

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. Vertical installation is possible optionally with or without cooling jacket. Cooling jacket is required for horizontal installation.
