Advantages: 1. Its structureis made of latest PE materials, and it is environment-friendly, nontoxic, sterile and rustproof. 2. As a substitute of traditional high water tower, it is full-automatic and easy to install, andwater supply lasts for a period whenpower failure happens. 3. Thetankis soldered by hot-melting, and in this way the tank is ensured to be airtight and non-permeable, compared to common metal devices. 4. It's economical, and costs only 40% of the expenses needed for traditional high water tower. 5. It's safe and energy-saving. When phase failure, under voltage, over-capacity, orlack of water happens, the self-protection device will work immediately. 6. When the tank works, the water can climb up to 5 or 6 floors. Operating Principle: A pressure tank can be as simple as a big chamber with one hole in the bottom for water to flow into. As the pump pushes water in, the air in the tank is compressed. At some point, called the cut-out pressure, the pressure switch interrupts the power to the pump and no more water enters the tank. Since there is compressed air above the water, there is enough force acting on the liquid to push it out of the tank, through the pipes, and all the way upstairs (possibly several flights of stairs) to the faucet. Market Prospects: As an economical and energy-savingdevice, PE-GX Full-Automatic Pressure Water Tank has been widely used in the villages and towns of China. Application Areas: Domestic water storage and water supply What Is A Pressure Tank? Why Do You Need It? When a house is built in an area that is not served by a municipal water works, a private well system is used. The well pumps used in most systems are quite powerful, often capable of delivering more gallons of water per minute than any single faucet could draw. Well pumps can burn out prematurely if they are made to start and stop more than necessary. By using a holding tank, the water can be used in a leisurely manner over a long time, and the pump will run briefly to refill the tank.
