The Oase AquaMax Eco Classic is an energy efficient, submersible solids handling pump with large pre-filter screen. Ideal for in-pond use where debris is delivered through the pump to a filtration system. These pond pumps have an external cage to prefilter the water and can be placed directly in ponds for waterfalls and water features. Built-in thermal overload and frost protection ensure your AquaMax will run for years. Solids-handling ability capable of handling particles up to 3/8" means fewer clogs and better water quality.
