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.
