AquaForte Dm Vario-S 22,000 Variable Speed Pump
specially made for applications in the water.
You can change the flow (and thus the energy usage) with the external controller from 30% to 100%.
The controller may also activate and deactivate the pump (pause button).
equipped for long-term use with a synchronous motor and a waterproof ceramic shaft.
automatic power-off protection for low battery situations.
When the impeller becomes obstructed, it enters a "lock" position where it stops using power and waits for the obstruction to clear.
This will stop the motor from burning out.
