The MF260S / MF265S series multi-spring Mechanical Seals, equivalent to the Flowserve RO (single), are designed for universal applications. Their compact design makes them ideal for use in all types of centrifugal pumps. Torque transmission from the retainer shell to the seal ring is facilitated by durable drive lugs.
With fully interchangeable parts, these seals are perfect for stock rationalization. All seals are factory-assembled and undergo dynamic testing to ensure consistent performance and reliability.
