Flexaseal Mechanical Seals FAQ
What is Flexaseal?
Flexaseal manufactures mechanical seals and sealing support systems for pumps, mixers, and other rotating industrial equipment. Its sealing solutions are used in demanding applications where controlling leakage and maintaining equipment reliability are critical.
What types of mechanical seals does Flexaseal manufacture?
Flexaseal offers standard and custom mechanical seals, cartridge seals, split seals, welded metal bellows seals, and seal support systems.
What is a mechanical seal?
A mechanical seal creates a seal around a rotating shaft to help prevent process fluid from leaking from pumps and other rotating equipment.
What is a cartridge mechanical seal?
A cartridge seal is supplied as a pre-assembled unit designed to simplify installation and reduce the potential for installation errors compared with assembling individual seal components in the field.
What is a split mechanical seal?
A split seal is designed so it can be installed around a shaft without completely disassembling certain pieces of equipment. This can significantly reduce downtime during seal replacement.
What is a welded metal bellows seal?
A welded metal bellows seal uses a metal bellows assembly rather than a conventional spring arrangement. These seals can be well suited for demanding applications involving extreme temperatures, pressures, or corrosive environments.
What industries use Flexaseal mechanical seals?
Flexaseal products are used in chemical processing, pulp and paper, oil and gas, power generation, wastewater treatment, manufacturing, and other industrial operations using pumps and rotating equipment.
Why do mechanical seals fail?
Mechanical seal failures can result from dry running, excessive heat, vibration, shaft misalignment, improper installation, incorrect seal selection, abrasive fluids, pressure problems, or poor operating conditions.
What are signs that a mechanical seal is failing?
Visible leakage is the most obvious sign, but operators may also notice increasing vibration, abnormal temperatures, repeated seal failures, contamination around the pump, or declining equipment performance.
Can the correct mechanical seal reduce pump downtime?
Yes. Selecting a seal designed for the fluid, pressure, temperature, shaft speed, and operating environment can significantly improve reliability and reduce repeated seal failures.
What is a seal support system?
A seal support system provides the operating environment required by certain mechanical seals. Depending on the application, it may control pressure, temperature, lubrication, flushing, or barrier fluid conditions.
Can Flexaseal provide seals for challenging applications?
Yes. Flexaseal offers custom-engineered sealing solutions for applications involving challenging temperatures, pressures, corrosive fluids, and other demanding process conditions.
Can mechanical seals be upgraded when recurring failures occur?
Often, yes. Repeated seal failures may indicate that the existing seal design or support system is not appropriate for the application. Evaluating the entire pump and process can identify opportunities for a more reliable solution.
Does Industrial Air Services provide Flexaseal mechanical seal support?
Yes. Industrial Air Services provides Flexaseal product selection, replacement seals, troubleshooting assistance, application support, and sealing solutions throughout Nashville, Murfreesboro, Franklin, Clarksville, Knoxville, Chattanooga, Bowling Green, and surrounding areas.
Can Industrial Air Services help select the correct Flexaseal mechanical seal?
Absolutely. Industrial Air Services can evaluate your pump, process fluid, shaft size, operating pressure, temperature, speed, and existing seal arrangement to help determine the appropriate Flexaseal solution.
Why choose Industrial Air Services for Flexaseal mechanical seals?
Industrial Air Services helps facilities select and support Flexaseal mechanical sealing solutions designed to reduce leakage, improve rotating equipment reliability, extend seal life, and reduce costly equipment downtime.
