Construction
Hydraulics
The angle of the propeller/impeller blades can be adjusted by hand. This makes it possible to adapt the unit to use in different conditions.
Motor
Surface-cooled motors (T motors) give off their heat directly to the surrounding fluid via the housing components and can be used in immersed state for continuous duty.
A sealing chamber protects the motor from fluid ingress. It can be accessed from the outside and can be monitored with an optionally sealing chamber electrode.
All filling fluids used are potentially biodegradable and environmentally safe.
The cable inlet of the T motors is longitudinally watertight. Cable lengths can be individually configured.
Seal
Fluid-side and motor-side sealing is possible in the following versions depending on the motor type:
- Version G: Two independently-acting mechanical seals
- Version K: Block seal cartridge with two independently acting mechanical seals

Commissioning
Operation with non-immersed motor:
Surface-cooled motors (T motors) can be non-immersed only if an operating mode is specified for non-immersed operation!
Dry-running protection system:
The hydraulics housing must always be immersed to prevent air from being drawn in. In the case of fluctuating fluid levels, the system should shut down automatically once the minimum water submersion is reached.
