Diaphragm pressure tank introduction ｜Aquasky

Aquasky's diaphragm tank is a pressurized water vessel that provides water pressure at a set range. The inside construction is divided into an air chamber and a water storage chamber, where the water and air are separated by a butyl rubber diaphragm allowing the water to expand and absorb pressure surges. The butyl rubber diaphragm plays an important role in the pressure tank. This process can reduce the number of pump startups required to keep the system pressure within the set range.

The gas-filled side of the tank contains Nitrogen. Nitrogen is less likely to migrate through diaphragm rubber, which means the pressure tank does not need to re-fill the air pressure once on the pressure tank in service. Nitrogen is a very stable gas against with temperature changes which means more consistent inflation pressures during the service life.

Aquasky pressure tank comes with a 304 stainless system connector of patented leaksafe technology, patented air valve design, pressure equipment directive certified welding structure, and triple coating rust protection with customized color. There is an extra layer of Virgin FDA polypropylene liner in the tank, which prevents water from directly touching the metal itself, so it is also suitable for drinking water systems.

When your pump is running, water into the pressure tank, it compresses the air in the tank until it reaches a preset level, usually the 40 to 60 PSI, which turns the pump off. When you turn on a faucet, air pressure in the tank forces water throughout the plumbing until the pressure drops to the preset pressure, usually the 20 to 40 PSI. That tells the water pump to turn on, and water is then drawn into the tank. Turn off a faucet, pressure builds until it is restored to its default shut-off level. The amount of water delivered by the pressure tank between the time the pump shuts down and the time it starts again is called the drawdown.

Aquasky’s product line includes the following products, the main difference is that applied to different systems and have different functions.
