摘要: A cascade waterfall or water fountain display with a compact, energy-efficient, low cost DC powered pump. An electronic controller controls the operation of pump and is also used to generate visual sound effects. The comprised motor shaft, housing in which mounted, gasket loosely seal within housing. has an aperture therein through motor's shaft passes. gasket's sized so that passes therethrough little, if any contact. impeller mounted for rotation pumping chamber. chamber plurality holes enters, outlet pumped by top waterworks structure. fit about allows some pass out pressure-relief pressure relief chamber, located between motor, port entered exits
