EHEIM CompactON Aquarium Pump

Work out your required flow and your total head, including pipe friction and any filter or UV losses, then pick the model that meets that flow at that head — the maximum flow figures here apply at minimal head, and flow falls to zero at the maximum head shown, so check the flow curve.

Yes — the materials used mean the range can be run in marine water without problems, as well as in fresh water.

Yes on the compactON 300, 600, 1000, 2100 and 3000, which all have an adjustable flow rate; the compactON 5000 runs at fixed output.

The compactON 2100, 3000 and 5000 can be modified for a dry mount installation outside the water; the smaller models are submersible only.

Maximum head runs from 0.6 m on the compactON 300, through 1.0 m, 1.4 m, 2.4 m and 2.7 m, up to 3.6 m on the compactON 5000.

12 mm on the 300 and 600, 16 mm on the 1000, 19 mm on the 2100 and 3000, and 25 mm on the 5000.

The flow curves for every model in the range are in the downloads section on this page.
