The double isolation shell consists of two metallic isolation shells placed one inside the other. A network of paths between the two isolation shells allows for an effective control via a pressure switch. Any damage to either the interior or exterior isolation shell will cause the pump to shutdown before any leakage would occur.The design of both isolation shells is made consistent with the design pressure, thus enhancing safety.

Also available in model SLM-AVO-TD.
