Reliable Double Mechanical Seal
Sam Seals India offers reliable sealing solutions for pumps, agitators, mixers, and rotating equipment where leakage control, safety, and uptime matter. A Double Mechanical Seal is the preferred choice when handling hazardous, toxic, corrosive, or high-temperature fluids, or when your process needs extra protection against seal failure. Compared to a single seal, it uses two sealing interfaces working together to reduce emissions, prevent product contamination, and increase equipment life.
In many industries—chemical, pharmaceutical, oil & gas, power, paper, and water treatment—double seals help maintain stable operation even under pressure fluctuations, dry-running risk, or abrasive media. With proper selection of seal faces, elastomers, and hardware materials, a double seal improves reliability while reducing unplanned shutdowns and maintenance cost.
At Sam Seals India, we focus on application-based sealing support so you get a solution that matches your media, speed, temperature, and operating pressure. Whether you need a cartridge style seal, balanced design, or a specific flush/plan arrangement, our goal is simple: safer operation and longer seal performance.
what is a double mechanical seal
A double mechanical seal is a sealing arrangement with two mechanical seals mounted in series—an inboard seal (process side) and an outboard seal (atmosphere side). Between them sits a barrier or buffer fluid that helps lubricate and cool the seal faces, while also acting as a protective layer. This design minimizes leakage to the environment and supports stable sealing in demanding applications.
Features:
- Double seal
- Balanced
- Independent of direction of rotation Cartridge unit
- Easy to install
- Single seals without connections with flush and with quench combined with lip seal or throttle ring.
- Additional variants available for ANSI pumps and eccentric screw pumps.
Application:
Generally cartridge multiple spring seal is used for slurries, sludges, syrups. The springs are isolated from media being sealed by dynamic elastomer.
- Single seals without connections with flush and with quench combined with lip seal or throttle ring.
- Additional variants available for ANSI pumps and eccentric screw pumps.
