Product Description1. Single and Dual seal configuration2. Balanced design3. Independent of direction of rotation4. Cartridge construction5. Designed for dry running applications6. Designed for top entry vessels, side

entry can be provided upon request7. Rotary unit with multiple springs

Technical Features1. Over all connecting dimensions are

tailor made to customer's specifications2. Can accommodate reverse pressure3. The seal design is unique as it closes

due to the hydraulic product pressure as well as overlaying barrier pressure

4. Rugged design to ensure long term reliability and operating life

5. Seals are assembled in cartridge construction for easy fitment and are also available in component design as per customer specification

MXS-110The MXS-110 is equipped in addition with a sleeve for trapping any abrasive particles from the seal face. Contamination of the medium in the container is thus ruled out. The sleeve can be cleaned through a flushing bore.

Please note: diameters (d to d ) increase to the 2 5

next possible design size.

Single Seal Variants MXS184Single seal

MXS184LSingle seal with integrated floating bearing.

MXS154All types of the MXS184 range available for unsteped shafts (all diameters). Seal identification: MXS154 ... Customized design or e.g. different drives (torque transmissions) are available. MXS164 / 194For glass-lined vessels. Dimensions as U164

Double Seal Variants MXS184-DDouble seal MXS184L-DDouble seal with integrated floating bearingThese seals are designed to be self-closing on the product side, i.e. they will remain closed even with pressure variations or a pressure reversal. Operation is optionally the same as for the single version. In view of the mechanical seal on the atmosphere side it can be used as a buffer pressurized double seal . The barrier pressure should be 0.5 … 1.0 bar (7.25 … 15 PSI) above pressure to be sealed.
