MTM111

Operative limits

Product description

Balanced mechanical seal, bidirectional, multisprings, with integral shaft sleeve. Due to the geometry with which it was designed, the springs never work in contact with the product, making it suitable for all applications with highly viscous liquid and solid parts. It is available in different material combinations. The metal parts can be produced in austenitic steels such as Duplex and super Halloy

Available stationary rings

S9
