Type

Submersible pump suitable for vertical or horizontal installation.

Hydraulics

Multistage submersible pump featuring a strap-design construction, semi-axial impellers, a built-in check valve, and a standard connection:

6" connection: NEMA standard
8" connection: NEMA connection

Discharge outlet with threaded flange and internal thread. All parts in contact with the pumped medium are made of corrosion-resistant materials.

Motor

Three-phase AC motor suitable for direct-on-line or star-delta starting:

Encapsulated motor with resin-impregnated windings and water-glycol fill.
Rewindable motor with PVC-insulated windings and water-glycol fill.

Motor bearings are self-lubricating.

Cooling

The motor is cooled by the pumped fluid. The pump must operate fully submerged.
Vertical installation is possible with or without a cooling shroud.
Horizontal installation requires the use of a cooling shroud. As-delivered condition
Hydraulic unit + motor (plug-and-play)
Drinking water-certified connecting cable (4 m, 8 m, or 10 m)
