The electronic Grundfos DP and EF pumps
21
incorporate a controller and motor-protective
functions. They only need to be connected to the
21
mains supply.

The controller offers the following benefits:
22
•
Built-in level and dry-running sensors.
22
•
Built-in motor protection.
22
22
•
Pump alternation.
23
If several pumps are installed in the same tank,
24
the control logic incorporated in the pump will
25
ensure that the load is distributed evenly among
25
the pumps over time.
