Aquaforte DM-Vario 20000
The Dm-Vario pumps are suited for outdoor use and are suited for wet & dry applications. With the external controller you can adjust the flow (thus the energy consumption) from 30% to 100%. The controller can also start/stop the pump (using a pause button). Provided with synchronous motor and wearproof ceramic shaft for long term use. Automatic power-off protection when running dry. If the impeller gets blocked, it will go into a "lock" position, in which, the pump does not use power and waits until the blockage is gone. This will prevent a motor burn-out.
