This continuous duty pump is designed to move large volumes of water silently and efficiently through filtration systems or to a waterfall, stream, or fountain. It incorporates a high efficiency vortex impeller in conjunction with a ceramic impeller shaft and bearings to provide energy savings while maintaining high output. This pump can be used submersed or inline, indoors or outdoors (note: when used inline, should be placed below the water level since it is not self-priming. Never run dry). Rotor assembly is removable for simple cleaning and maintenance. Unique design reduces the frequency of pump cleaning while maintaining optimum water flow. 2" outlet. 5.5 Amps. 675 W. 5700 gph max output. 22.5' max head height.
