Mechanical Seals

Style 17

Sturdy Single Spring Component Seal

The Single Spring serves to keep the sealing faces in contact and positively transmits the drive evenly 360º around the full circumference of the rotary face. This is accomplished by specially designed ends of the spring, which provide an interference fit. Then as the shaft rotates the spring ends further increase their grip. This compression spring is wound either right or left hand depending on shaft rotation.
