Benefits mechanical seal 4eys

The axial spring force is evenly distributed over the entire circumference of the primary ring. This minimises wear and contributes to a long seal life.

Open design of the area around the springs to prevent the springs from being blocked by deposits.

Large dynamic O-ring; flexible and less sensitive to start-up conditions. High resistance to modern, synthetic thermal oils.
