Description

Micro exposed diaphragm seals are designed for the application where extreme level of sanitary cleanliness and purity is critically required. These diaphragm seals are generally used across food, beverages and pharmaceutical industries. These seal avoids dead space and cavity so that solidification, contamination as well as bacterial & fungal formation is eliminated. This design also allows fast, efficient removal and installation for flushing or changing process media, line cleanout and equipment washout situations.
