Eheim Compact On 600 Pump

The EHEIM compact ON aquarium pump is characterized by its name through a compact design and is thanks to the included accessory bag appropriate for versatile use. The EHEIM compact ON 2100-12000 can also be modified for the use outside of the water. Thanks to the high quality material it is also possible to use them without problems in marine water.

For even more flexibility, the flow rate is adjustable for all models.

Advantages of the EHEIM compact ON

Compatibility

A universal pump for fresh and marine aquariums, run submerged. EHEIM publish 600 litres an hour maximum, adjustable down to 250, a maximum head of 1 metre and 7 watts at 50 Hz. It measures 38 × 72 × 62 mm (W × H × D) with a 2 metre cable, and the suction-side connection is 12 mm.

That output range suits feeding a small skimmer or reactor, driving a closed loop or a return, running water changes and top-ups, or adding flow to a small tank. Flow is set either by turning the controller on the pump cover or by turning the suction basket.

Safety & Precautions

From EHEIM’s compactON 300 / 600 / 1000 manual:

• The pump must not run dry.
• Indoor use only, for aquariums, and not for commercial or industrial use.
• Water temperature must not exceed 35 °C.
• Maximum immersion depth 1 metre. The pump is protection class II and rated for continuous submersion.
• Fit it below the water line, on the bottom or the inside wall of the tank.
• It has no switch: the pump starts the moment the plug goes in.
• Disconnect every device from the power supply before any maintenance.
• Do not clean it with hard objects or aggressive cleaners, and do not put any part of it in a dishwasher.

What’s in the Box

• compactON 600 pump with its pump cover and flow controller
• Hose connecting piece

• Suction basket

The suction cups screw into the openings in the motor body; wetting them first makes that much easier. The suction basket clips onto the connecting piece inside the pump cover.
