Type 5281 is part of the 5280 hygienic vessel seal family. Please find general technical and hygienic design features of this family in the description of Type 5280. The Type 5281 was especially developed for applications on glass-lined reaction vessels with a glass-lined agitator shaft. To enable this, all product-wetted materials of the seal need to be of nonmetals. Due to the special design features of the 5280 seal family, this could be achieved by just building a silicon carbide insert into the cartridge flange. All other components and features are similar to Type 5280.
