Surge tanks are mostly used in mud mixing systems on offshore drilling rigs and supply vessels. The Lion-designed surge tank, combined with our mass flow fluidiser and backflow prevention unit, ensure a quick and efficient mixing of barite and bentonite. The Lion backflow prevention unit eliminates the backflow of drilling mud into the mass flow fluidiser and into the surge tank if the suction valve on the shearing mixer is accidentally left open when mixing stops. The backflow prevention unit utilises a vacuum transducer that senses when vacuum has been compromised and closes the automated valve on the shearing mixer suction side.
Designed by Lion Bulk Handling, this solution is by far the most cost-effective way to discharge the material in an efficient, safe and clean manner.
The tanks can be delivered with several class approvals, including LR, GL, ABS and ASME.
