An electrical alternator is used on a duplex pump application where automatic electrical cycling of the pump is desired for added protection in residential or commercial applications. With one pump operating to handle normal flow, a second pump becomes operational in the event the water level continues to rise. The built-in alarm system, a standard feature, can be connected to sound when the second pump becomes operational (three-float switch system) or independently (four-float switch system).
