Type
Submersible pump suitable for vertical or horizontal installation.
Hydraulics
Multistage submersible pump with sectional construction, featuring radial impellers and an integrated non-return valve. Pressure connection with threaded flange and internal thread. All wetted parts are made of corrosion-resistant materials.
Motor
Single-phase or three-phase AC motor for direct-on-line starting. The oil-filled motor is rewindable and equipped with self-lubricating bearings.
Cooling
The motor is cooled by the surrounding 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.
