COMPONENTS & SOLUTIONS FOR FLUID HANDLING

DESCRIPTION

Single mechanical seal, unbalanced, independent of the direction of rotation, with single leaf spring; it is manufactured in accordance to UNI EN 12756 (ex DIN 24960) standard. Its versatility in the variety of materials and the design of the leaf spring, allows it to be widely used not only on heavy duty machines at medium pressure but also in presence of highly viscous liquid.
It is available in different configurations. The high torsion resistance and the small working lenght make it of universal application. It is available in multispring configuration as well.
