Collection: Eheim Water Pumps

Eheim's CompactON pumps are compact submersible water pumps with a dial to set the flow, so one pump can be tuned to the job instead of throttled with a valve. Two sizes are listed: the CompactON 300, rated up to 300 L/h for small tanks and filter feeds, and the CompactON 2100, rated up to 2,100 L/h for sump returns and larger systems. Size for the flow you need at your head height, not the maximum on the box.
