Other contenders

  • EHEIM compactON 2100

    Choose the compactON 2100 for external installation with manual flow adjustment. Its maximum head is 2.4 m at 50 Hz; use the curve to check output at your lift.49

Buying advice

  • Choose by the flow your plumbing needs at its actual lift. The headline flow and maximum head are separate limits.1
  • Check your power supply against the regional model: the compactON head and power figures here are specified at 50 Hz.9

For turning the flow down to suit the tank

Choose the compactON 600 for an underwater return when you need to adjust the flow mechanically to suit the circuit.3

For plumbing the pump in line, outside the water

Choose the universal 300 for a modest flow external return with a short lift. Consider the compactON 2100 when you also want manual flow adjustment outside the water.1249
