Principle of operation
The skimmer with venturi pump has to be placed in a separate filter tank. The water is pumped to
the skimmer by the venturi pump. The pump draws water from the filter tank and mixes it with air.
Within the pump housing, the bubbles are cut into very fine pieces by the Aqua Medic
3D-needle
wheel
. The air/water mixture is pumped back into the skimmer. The treated water flows through
the outlet or drain valve out of the skimmer back into the filter tank.

Venturi pump
The
DC Runner
series of magnetically coupled centrifugal pumps are very quiet in operation. They
have fully encapsulated synchronous motors. All materials are saltwater resistant.
The polished ceramic shaft and bearing is practically wear-resistant, ensuring a long operating life.
The pumps can easily be taken apart for cleaning. The direction of the rotation is controlled
electronically. This enables a very efficient operation.
3.1. Connections
Suction side:
The included air injection nozzle is placed at the pump’s suction side.
Pressure side:
The pressure side is connected to the skimmer by the existing connection with
union nut (13). Please make sure that the O-ring (14) is placed into the groove.

The pump DC Runner 5.0 is operated by an electronic safety transformer at AC 100 – 240 V / 50 –
60 Hz and 24 V DC output. Power consumption of the pump is 10 watts, protection rating is IP X8.
To open the pump, remove retaining plate and release the pump head (7) by turning it.
