MTM111

Operative limits

Product description

Microtem MTM111 is a balanced mechanical seal with an integrated shaft sleeve, bidirectional with multiple springs. Thanks to the design geometry of this mechanical seal, the springs of the MTM111 never come into contact with the product being contained, making it suitable for all applications involving highly viscous liquids and suspended solid particles.

The MTM111 mechanical seal produced by Microtem is available in different material combinations, designed to adapt to a wide variety of machinery and materials. The metallic parts of the MTM111 component seal can also be made from super austenitic steels such as Duplex and Hastelloy.

Available stationary rings
