This submersible pump was designed with ponds in mind and has a max flow rate of 2377 gallons per hour. Its maximum head pressure will move water up to 11’ in height while using a measly 95 watts. Designed with a shaft consisting of ceramic materials, it’s perfect for running wet/dry systems in fresh or saltwater aquariums without seizing. Pump comes fitted with a netted pre-filter to prevent debris from causing unwanted back pressure on the pump. Centrifugal impeller design along with a high flow rate makes this one of the most energy-efficient pumps that you will find. 32 feet and 9 inch long cord.
