How a Diaphragm Expansion Tank Works

When water is heated in a closed system, it expands. Water is not compressible, therefore, the additional water volume created has to go someplace. When an expansion tank is installed, the excess water enters the prepressurized tank (figure 3). As the temperature and pressure reaches its maximum, the diaphragm flexes against an air cushion (air is compressible) to allow for increased water expansion (figure 4). When the system is opened again or the water cools, the water leaves the tank and returns to the system.

Single Diaphragm Pressure Vessel

A range of reliable vessels, available in 10 and 16 bar pressure ratings and sizes from 3  to 200 litres. The series is constructed of a virgin polypropylene liner combined with an NSF Certificated high grade butyl diaphragm, which is held against the wall of the tank with a steel clench ring. The tanks design includes rounded internal parts to prevent piercing and a unique connection providing a dual water/air seal for a complete leak and maintenance free vessel.


Solar Aqualeader tanks are quality tested at several stages on the production line to insure the structural integrity of every tank. Solar Aqualeader  tanks represent the best value for the investment and are the best quality pressure vessels available today.
