The Type CK 725 is a dual-pressurized, liquid-lubricated cartridge seal for top-entry mixing and agitating equipment. A value-engineered design, high level of standardization and broad material options make this seal a cost-efficient solution for general-duty applications in the chemical and pharmaceutical industry. Standard versions are compliant with vessel seal standard DIN 28138 Parts 1 and 3. They are designed for use on steel-made agitated chemical reaction vessels to DIN 28136, to fit on a mounting flange to DIN 28141 and agitator shaft end dimensions to DIN 28154. Hardware adaptations to fit to non-DIN equipment are available on request.
