Eheim compact ON 3000 Universal Aquarium Pump (3000 l/h) The Eheim compact ON 3000 is a compact, powerful, and whisper-quiet universal aquarium pump delivering an adjustable flow rate from 1800 up to 3000 l/h at just 55 watts. Compared to the pumps of the Eheim compact and compact+ series, the power consumption was again improved by up to 50% — making the compact ON 3000 one of the most energy-efficient pumps available in its class. The compact ON 3000 can also be modified for use outside of the water — making it equally suitable for sump returns, external circulation, and in-tank powerhead applications. Thanks to its high quality material it is also possible to use it without problems in marine water. The compact ON 3000 features an adjustable flow rate for flexible control of water movement, a ceramic bearing for silent long-lasting operation, and comes supplied with an accessories bag including a suction basket and threaded coupling for immediate versatile use. Fastened securely with robust suction cups, it can be positioned quickly and stably in any aquarium or sump setup.
