We use carbon and SIC as the raw materials for manufacturing the rotary and stationary seal parts. Due to the characteristics of the SIC, the product is endowed with the performance of stable chemical properties, low thermal expansion coefficient and good wear resistance. Besides that, the product is equipped with strong cast iron which gives it long service life. As for the secondary seal, we use EPDM to help the product gain the advantages of weather resistance, ozone resistance, heat resistance, acid and alkali resistance.

For better satisfying the needs of customers, the product can be provided with different shaft sizes ranging from 24mm to 100mm.

The flygt pump seal is designed with the upper seal and lower seal. By using the Tunsten carbide, Tungsten carbide, and viton, the upper and the lower of the seal can be fitted smoothly, which ensures low leakage rates. When being operated in a controlled environment, the upper seal offers very high resistance. As for the lower seal, it features sturdy design and should be able to cope with fibrous clogging matter, hard abrasive particles, and chemically aggressive media, etc. The product is designed to accommodate short shaft overhang. Torque locks and drivers are independent of the shaft rotation and pump pressure acts as a closing force on the seal. What’s more, the frame of this Flygt mechanical seal is made of aluminum shell instead of old plastic frame, making the seal stronger and helping to against rusty problem.
