Design Features:

1，Dual face /Multi- spring/spring protection/Balanced /all directions rotation/Part Cartridge/Static
2, Spring is not in contact with the media, in order to overcome the high viscosity of the material easy to crystalize blocked to protect the flexibility of the loop compensation, extending the compensation ring seal life, mechanical seal flush with external auxiliary structure, thereby improving the sealing condition, spring does not rotate, so that the seal can carry larger loads, cavitation and evacuation, cartridge structure, easy to install.
