High-performance Modular Mixer and Agitator Seal for Steel Chemical Reaction Vessels — Standard Solutions Comply to Vessel Seal Standard DIN 28138 – ISCK728

Type ISCK 728 is a versatile, high-performance cartridge seal solution for steel 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 728 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 28141 and agitator shaft end dimensions to DIN 28154. Modifications of adaptive hardware to fit non-DIN mixers or special equipment are available on request.

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.
