OASE AquaMax Eco Classic Pumps are OASE's new entry level pond pumps for powering pond filters and waterfalls. New pump technology gives the AquaMax Eco Classic the same dependability of its predecessors, but with energy savings up to 50%. Like previous AquaMax pumps, the AquaMax Eco Classic is virtually clog-proof and is designed for use on the pond bottom to move organic waste to the pond filter for removal from the pond ecosystem.
