Construction

Submersible pump for vertical or horizontal installation.

Hydraulics

Multistage submersible pump with radial or semi-axial impellers in sectional construction and integrated non-return valve. Discharge port with threaded flange and female thread. All parts that come in contact with the fluid are made of corrosion-free materials.

Motor

Single-phase or three-phase current motor for direct starting. Sealed motor with lacquer-insulated, resin-covered winding, water-glycol filling and self-lubricating motor bearings.

Cooling

The motor is cooled by the pumped fluid. Always operate the pump in a submerged state.
Vertical installation is possible with or without cooling jacket.
Horizontal installation must be performed in conjunction with a cooling jacket.
