OASE Eco Premium AquaMax Pond Pumps are OASE's newest upgrade to the AquaMax pump series. This pump has no equal for powering pond filters and waterfalls. New electronic pump and magnet technology gives the OASE AquaMax Eco Pond Pump the same dependability of its predecessors, but with energy savings up to 50%. The AquaMax OASE Pumps feature an adjustable secondary inlet in order to draw water into the pump from a remote area or for using an in-pond skimmer. Like previous OASE pumps, the Premium OASE AquaMax Pond Pumps are virtually clog-proof and designed for use on the pond bottom to move organic waste to the pond filter for removal from the pond ecosystem.
