COMPONENTS & SOLUTIONS FOR FLUID HANDLING

DESCRIPTION

Balanced mechanical seal, bidirectional, with integral shaft sleeve and with a single spring. Due to the geometry with which it was designed, the spring never works in contact with the product, making it suitable for all applications with highly viscous liquid and solid parts. Made according to UNI EN 12756 (ex DIN 24960),it is available in different material combinations. The metal parts can be produced in austenitic steels such as Duplex and super Halloy.
