FAQs about Sanitary Water Systems
-
Anti-water hammer membrane tanks are tanks built for civil and industrial water systems where high operating pressures are required. They are particularly suitable for preventing the serious consequences of water hammer, i.e. the pressure wave that is created inside a pipe when an incompressible liquid, such as water, is stopped abruptly or instantaneously (for example: the rapid closing of a valve or the stopping of a pump).
-
The CIMM expansion vessels suitable for use with drinking water are the ones with the interchangeable membrane that show the drinking water eligibility sign on the vessel label. In these vessels, the water is contained entirely inside a special bag shaped rubber membrane and never coming in contact with the metal body of the vessel.
