Pump Vacuum Retainer Features:
The pump vacuum maintainer utilizes the principle of water-gas displacement, drawing water through exhaust to automatically form and maintain a vacuum in non-self-priming pumps or siphons. It has the capability to serve multiple pumps simultaneously with one unit. The pump vacuum maintainer operates automatically, requiring no human intervention or electricity, and only a small amount of tap water is needed during operation (the used tap water can be recycled back into the pool for continued use). It is an ideal equipment for achieving energy conservation and microcomputerized automation control in water supply and drainage pump stations, water purification plant filter siphons, and other siphon water conveyance systems.
