R-609

Mechanical seal R-609

The R-609 mechanical face seal is designed for use at high temperatures (up to 425 ° C / 800 ° F) in pumps without costly and time consuming seal chamber modifications. Applications include hot hydrocarbons, aqueous solutions, aromatic fractionation products, crude oil fractionation products, and heat transfer fluids. Execution material: Rotary ring (SiC / Carbon / TC), Stationary ring (SiC / TC), Secondary seal (Flexible Graphite), Metal bellows (SUS316L / AM350 / InconeI718 / Titanium / Hastelloy-C / AIIoy-20) Other parts ( SUS304 / SUS316 / Titanium / Hastelloy-C) Operating limits: Pressure: ≤2MPa (single-layer bellows) ≤6.9MPa (double-layer bellows) Speed: ≤25m / s Temperature: -75ºC ~ + 425ºC Mechanical seal for Wilo pump, К, КМ, Х, АХ, АХП, АХ, Calpeda, DAB, Ebara, Grundfos, for pump KSB, Allweiler, SALMSON, ACD Cryo, Flygt, IMP Pumps, LOWARA, PENTAX, Foras, Fristam, for pump SPERONI, ZENIT, Inoxpa, JL, Johnson pump, KOLMEKS, Pedrollo, SAER, Vulcan, WQ, WQK, for Tuchenhagen pump, ALFA LAVAL, Donjoy, Mission Magnum.
