Lianyungang Zhenxiang Electric Equipment Co., Ltd. is a manufacturer of vacuum maintainers. Our pump vacuum maintainers are suitable for various self-priming (negative pressure suction) pump units and pump stations, waterworks filter pond siphons, and vacuum extraction and maintenance for other siphon water conveyance pipes. They reduce the intermediate process between stopping and starting the pump, shorten the time, and can initiate water supply from non-operational pumps. The Lianyungang Zhenxiang Electric ZBQ type pump vacuum maintainer is a derivative design of the WDF type pump vacuum maintainer, overcoming the defect of easy return of condensate to the pump body during air exchange in the old WDF type. It shortens the air extraction time and ensures rapid vacuum formation in the pump suction pipe. The pump vacuum maintainer utilizes the water-gas displacement principle and the method of automatic drainage and air extraction to achieve automatic formation and maintenance of vacuum in non-self-priming pumps or siphons. It has the capability to supply multiple pumps with a single maintainer, making it more reliable, convenient, and energy-efficient than traditional vacuum pump air extraction methods. It fulfills the desire for automatic water intake without a bottom valve in various water intake pump units and pump stations. The pump vacuum maintainer operates automatically and requires no special operator; it only needs a small amount of tap water (the used tap water can still be returned to the pool for reuse) and a little single-phase (220V) electricity. The pump vacuum maintainer is an ideal device for achieving energy saving and microcomputerized automation control in water supply and drainage pump stations, water purification plant filter pond siphons, and other siphon water conveyance pipes, and it is also the ideal equipment for maintaining pump vacuum in non-self-priming pump stations at home and abroad.
