The ME280D / ME285D series multi-spring mechanical seals are engineered for demanding industrial applications, available in both balanced and unbalanced configurations. Their compact, space-efficient design ensures compatibility with a wide range of centrifugal pumps across multiple industries.
Reliable torque transmission from the retainer shell to the seal face is achieved through robust, precision-engineered drive lugs, ensuring stable operation under varying load conditions. The seals feature fully interchangeable components, enabling effective stock rationalization and simplified maintenance.
Each seal is factory-assembled and dynamically tested to stringent quality standards, ensuring consistent performance, operational reliability, and extended service life in continuous-duty applications.
