Frequently Asked Questions
1. Which Flygt pump models are compatible with the TS-X mechanical seal?
The TS-X machined mechanical seal is designed as a replacement seal for a range of Flygt submersible pump models used in wastewater and industrial applications. Compatibility depends on the pump model and shaft size. Always verify the seal dimensions or consult TRISUN's technical team before ordering.
2. What material options are available for the TS-X Flygt pump seal?
The TS-X seal is available in several seal face combinations, including Silicon Carbide (SiC), Tungsten Carbide (TC), and Carbon, allowing users to select the most suitable option based on operating conditions, fluid abrasiveness, and temperature requirements. Elastomer options such as NBR, EPDM, and Viton (FKM) are also available.
3. Can the TS-X mechanical seal handle abrasive wastewater and slurry applications?
Yes. The TS-X seal is specifically designed for demanding environments such as wastewater treatment, sludge transfer, mining, and slurry handling. For highly abrasive media, SiC/SiC or TC/TC seal face combinations are recommended to maximize wear resistance and service life.
4. How do I choose the correct TS-X seal size for my Flygt pump?
To select the right TS-X seal, identify your Flygt pump model number, shaft diameter, and existing seal dimensions. Matching these specifications ensures proper fit and optimal sealing performance. If you are unsure, TRISUN can assist in confirming the correct replacement seal.
5. What are the common causes of mechanical seal failure in Flygt pumps?
Mechanical seal failures are often caused by dry running, excessive vibration, shaft misalignment, abrasive particles in the pumped media, improper installation, or operating beyond recommended pressure and temperature limits. Regular inspection and selecting the appropriate seal materials can help extend seal life and reduce downtime
