The main parts of the seal (spring and seal ring) are located on the static side. Because of the simplified shape of rotary parts, they have little influence on the dynamic balance of rotary equipment. This seal is suitable for high-speed, high-rpm equipment.
The “RAB” type uses synthetic rubber for packing.
