The QT HA211 single-spring mechanical seal offers significant advantages in abrasion resistance,anti-

clogging capability, stress management, and environmental adaptability. It demonstrates exceptional performance in industries such as:

1.Pulp and paper manufacturing

2.Water and wastewater treatment

3.High-viscosity fluid handling

4.Pulp suspension processing
