Expansion vessels

PlaceHolder (2)

In practice, water cannot be compressed and therefore, any increase in water volume must be accommodated in an expansion vessel designed and sized for that purpose.

Expansion tanks can be used as pulsation dampers, expansion vessels or in pump pressure systems providing storage of pressurised water.

Masterflow stocks a range of sizes in various mounting configurations.

Standard construction is carbon cold compressed steel with natural rubber or butyl membranes. This has many advantages over open vented systems as it generates less heat loss, less resultant corrosion and is much easier to install.
