Bladder Surge Tank


  • Product Catalog:
Up to 100 BAR | 8 – 150,000 L


A Bladder Surge Vessel is a surge control device installed with a butyl rubber bladder. A pre-charge pressure is calculated to give the required elasticity to push the water into the system following a pump trip. As there is no contact between the compressed air and the water, there is no dissolution. Thus, there is no requirement for a permanent regulation system including compressors, etc.
Once the vessel has been commissioned and the correct pre-charge has been introduced, the vessel will operate automatically, emptying when called upon and refilling with the return waves until naturally reaching its steady state balance.

Product Features

The vessels can be installed either horizontally or vertically.
In order to verify the water level in the vessel, it is normally equipped with a level indicator as well as a manometer to verify the initial pre-charge pressure.
