Stainless Steel Case & Stainless Steel Internals

The standard Blanes chemical seal is built up from various modules, around a 74mm diaphragm with a 63mm active diameter. This large diaphragm provides greater sensitivity and displacement to improve performance across the board. This design offers great flexibility at a competitive price allowing close matching of process and instrument requirements to provide the right seal for the application.

Chemical Seals form a barrier between the instrument and the pressure medium. Their main uses are to protect against blockage of the instrument’s pressure entry, and to protect against corrosion.
