COMPONENTS & SOLUTIONS FOR FLUID HANDLING

DESCRIPTION

Single mechanical seal, balanced, independent of the direction of rotation, with metal bellows.
Available in different solutions, it is widely used in applications with fluids containing solid medium particles or with high viscosity fluids.
The seal presents no blocking problems, as the metal bellows is the only elastic element. In special solutions it can be used at high temperature operating.
It is manufactured in accordance to UNI EN 12756 (ex DIN 24960), and it is available with metal parts in Hastelloy, Inconel or AM350.
