Versatile Seal Face and Elastomer Choices

Select from a range of seal face materials-Carbon, Silicon Carbide, Tungsten Carbide, and Ceramic-to perfectly match your application's requirements. Pair these with tailored elastomers like Nitrile, EPDM, Viton, or Neoprene, providing reliable resistance to a diverse array of chemicals and fluids. These combinations ensure optimal performance and extended service life, even in stringent operating conditions.

Effortless Installation and Bi-Directional Operation

Designed for ease of use, these mechanical seals require no shaft steps or sleeves, streamlining the installation process and reducing downtime. Their bi-directional design means they operate efficiently regardless of shaft rotation direction, making them suitable for various pump types like water, submersible, sewage, and chemical process pumps.

Durable, Corrosion-Resistant Design

Constructed with top-grade Stainless Steel 304/316 springs and PTFE components, the seals stand out for their corrosion resistance and stable performance in environments with challenging fluids. The high-polish finish of the sealing faces minimizes friction and wear, further enhancing longevity and reducing maintenance requirements.

FAQ's of Elastomer Bellow Mechanical Seals:

Q: How do I choose the right seal face and elastomer combination for my application?

A: The ideal seal face and elastomer depend on the chemicals, temperatures, and operating conditions in your system. For abrasive or corrosive fluids, materials like Silicon Carbide or Tungsten Carbide with Viton or EPDM elastomers are advisable, while water and non-aggressive media often suit Carbon or Ceramic faces with Nitrile.

Q: What is the advantage of the bi-directional shaft design in these seals?

A: The bi-directional design allows the seal to function properly regardless of shaft rotation, making it universally applicable in pumps where direction may change or is not predetermined, enhancing installation flexibility and reducing inventory requirements.

Q: When should Elastomer Bellow Mechanical Seals be used instead of conventional seals?

A: These seals are best employed when you require easy installation, dependable sealing under variable loads, reliable corrosion resistance, and long-term use with minimal maintenance, such as in water, sewage, chemical, or submersible pump applications.

Q: Where can these mechanical seals be installed?

A: They are suitable for a variety of pumps, including water pumps, submersible and sewage pumps, and chemical process pumps, across numerous industries. Their broad chemical compatibility and ease of installation make them versatile for standard and critical service environments.

Q: What is the installation process for these bellow seals?

A: Installation is straightforward and doesn't require shaft modifications, such as steps or sleeves. Simply place the seal onto the shaft following manufacturer guidance, ensuring correct alignment for a secure fit and optimal sealing performance.

Q: How do these seals help prevent leakage and extend equipment life?

A: The combination of precision-engineered faces and robust elastomers delivers a highly reliable seal, even under fluctuating pressures and loads, greatly minimizing leakage risks and reducing the need for frequent repairs or maintenance.

Q: What are the operational limits in terms of temperature, pressure, and speed?

A: These seals operate effectively in temperatures from 20C to 120C, support pressures up to 10 bar, and handle shaft speeds up to 25 meters per second, accommodating most pumping systems' requirements in industrial environments.
