Mechanical seal R-680 (676 / 670 / 680) Mechanical seal type R-680 with a rotating bellows made of AM350 alloy provides corrosion resistance in aggressive environments with high levels of abrasives. Its design is intended for use in the chemical, water and wastewater, pulp and paper and municipal industries. The sealing ring does not have a compensation function, so the bellows can move without moisture. Analogue John Crane 680, MB-J01, HW680. Operating limits: Pressure: ≤2.1 MPa Speed: ≤25 m/s Temperature: -20ºC ~ + 200ºC Versions: Rotating ring (SiC / Сar (carbon) / TC) Stationary ring (SiC / TC) Rubber (VITON / PTFE) Metal parts (AISI316L / AM350 / Inconel718 / Titanium / Hastelloy-C / AIIoy-20)
