Pressure tanks are containers that hold gases, vapors, and fluids at high pressures. They are used in many industrial applications for chemical, pharmaceutical, food and beverage, recreational and oil and fuel processes, and they are also often found in conjunction with well systems that supply water to residential homes or buildings.

Types of Pressure Tanks
Well Pressure Tank
In a well pressure tank, there is water at the bottom and compressed air at the top. When one opens a faucet, compressed air applies pressure to the water, causing it to flow out of the tank through pipes. The pump's activity causes water from the well to fill the tank's bottom. The air at the tank's top becomes more compressed as the water level increases. The pump turns off at a maximum pressure of about 50 - 60 psi.
Bladder Pressure Tank
A bladder pressure tank features two chambers, one for compressed air and one for water. The bladder component is like a self-contained, expandable balloon filled with water. The tank sensor activates the pump. Since bladder pressure tanks don't have a diaphragm that could malfunction, they normally last longer than diaphragm pressure tanks.
Diaphragm Pressure Tank
A diaphragm pressure tank has a pressurized air chamber and a water chamber. A rubber diaphragm separates the two chambers. The diaphragm is built to increase the water level and cause the pump to turn off. Despite the effectiveness of diaphragm pressure tanks, they can fail if the diaphragm separates from the tank's sides and causes a sharp drop in water pressure. The diaphragm of a tank may also fold over on itself, which could lead to the pump running nonstop and wearing out.
Air-Over Water Pressure Tank
In an air-over-water pressure tank, the water and air charge are stored in a single, galvanized pressure tank. They often have an inner coating to prevent corrosion. The tank is glass-lined or epoxy-coated to keep the tank from rusting. In a single tank, air and water are not separated. Although air-over-water tanks are larger, they have the capacity of a smaller tank. Therefore the pump operates frequently and wears out prematurely.
Advantages of Pressure Tanks
- Pressure tanks are used in nuclear and mining industries. They securely store liquid gases and flammable chemicals.
- Pressure tanks are used for distillation and water heating.
- Using pressure tanks in water distribution systems can increase pump lifespan by softening hydraulic shocks. This is because the air inside the vessel is compressed when pumped water enters.
Applications of Pressure Tanks
- The chemical industry may use pressure tanks to create chemical reactions. In the chemical industry, numerous pressure vessel types may be used simultaneously.
- The energy industry uses pressure tanks to limit harmful gasses. Only some facilities use a reactor pressure tank. Reactor Pressure Vessels are special pressure vessels used in nuclear power plants (RPVs).
