Mechanical seal Type-680 (676/670/680) Mechanical seal type Type-680 rotary bellows c AM350 alloy provides corrosion resistance in aggressive environments with high levels of abrasives. Its design is intended for use in the chemical, water and waste water, pulp and paper industries and utilities. The sealing ring has no compensation function, so bellows can move without moisture. Analogue of John Crane 680, MB-J01, HW680. Operating limits: Pressure: ≤1, 1 MPa Speed: ≤15 m/s Temperature: -20°C ~ + 200°C Versions: The rotating ring (SiC / SAR (carbon) / TC) Stationary ring (SiC / TC) Rubber (FKM / PTFE) Metal parts (AISI316L / AM350 / Inconel718 / Titanium / Hastelloy-C / AIIoy-20)
