Mechanical seal R-680

Mechanical face seal R-680 (676/670/680) Mechanical face seal type R-680 with a rotating bellows made of alloy AM350 provides corrosion resistance in aggressive environments with a high level of abrasives. Its design is intended for use in chemical, tap and waste water, pulp and paper and municipal industries. The O-ring has no compensation function, so the bellows can move without moisture. Analogue of John Crane 680, MB-J01, HW680. Working limits: Pressure: ≤2.1 MPa Speed: ≤25 m / s Temperature: -20 ° C ~ + 200 ° C Options: Rotary ring (SiC / CAR (carbon) / TC) Stationary ring (SiC / TC) Rubber (VITON / PTFE) Metal parts (AISI316L / AM350 / Inconel718 / Titanium / Hastelloy-C / AIIoy-20)
