Submersible pump for vertical or horizontal installation.

Hydraulics

Multistage submersible motor pump with NEMA (6" and 8") or standard connection (10") with radial or semi-axial impellers with sectional construction. Integrated non-return valve. All parts that come in contact with the fluid are made of corrosion-free materials.

Motor

Rewindable three-phase AC motor with PVC-isolated winding and a water-glycol filling for direct startup. Hydraulic connection as NEMA (6" and 8") or standard connection (10"). Sealing of motor shaft with a mechanical seal made of carbon/ceramic material. Self-lubricating motor bearing. Thrust bearing with rockers for absorption of high axial thrust. Negative axial thrust is absorbed by the rotating seal bearing.

Cooling

The motor is cooled by the pumped fluid. The motor must always be immersed when operated. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. Horizontal installation must be performed in conjunction with a cooling jacket.
