High-performance Modular Mixer and Agitator Cartridge Seal for Glass-lined Chemical Reaction Vessels — Standard Solutions Comply to Vessel Seal Standard DIN 28138 – Type ISCK738
Type ISCK 738 is a versatile, high-performance cartridge seal solution for glass-lined vessels applicable in various industries, including high-purity pharmaceutical applications. High-end materials, balanced faces and a thrust bearing, in combination with a special sleeve design, secure stability of the seal settings and proper operation even in heavy-duty environments. Type ISCK 738 is available in liquid-lubricated (W), gas-lubricated (G), dry-running (D) or with a unique gas/dry face combination (GD). Advantages of contacting dry-running seals include freedom from contamination by barrier liquid and a low face wear rate, together with a cost-efficient, easy-to-install (gas) supply system. Advantages of gas-lubricated versions (G, GD) include the non-contacting, wear- and particle-free operation in addition, which makes these seals the perfect solution for high-end pharmaceutical applications. The GD design reduces the overall barrier gas consumption compared to G version.
The special modular design ensures maximum application flexibility through interchangeable sealing components. The standard cartridge design is available to fit on top-entry, steel agitator vessels to DIN 28136, with mounting flange to DIN 28137-2 and agitator shaft end dimensions to DIN 28159. Modifications of adaptive hardware to fit non-DIN mixers or special equipment are available on request. Components are standardized with seal Type ISCK 728 for steel vessels.
All versions are suitable for operation in potentially explosive atmospheres. Depending on individual explosion protection requirements, the seal operating limits may differ from the parameters given below.
Product Description Type ISCK738
The Type ISCK738 vessel seal range is the high performance DIN cartridge solution for glass lined vessels. The special modular design ensures maximum application flexibility through interchangeable sealing components. The cartridge design is standardised to fit on top entry, glass lined agitator vessels to DIN 28136, with mounting flange to DIN 28137-2 and agitator shaft end dimensions to DIN 28159. Modifications to fit non-standardised equipment are also possible.
All versions are suitable for operation in potentially explosive atmospheres. Depending on individual explosion protection requirements, the seal operating limits may differ from the values given in this data sheet. Consult Iseal for more information
