The R-609 mechanical seal is designed for use in high temperature applications (up to 425°C / 800°F) in pumps without costly and labor-intensive seal chamber modifications. Applications include hot hydrocarbons, aqueous solutions, aromatic fractionation products, crude oil fractionation products and heat transfer fluids. Material: Rotating 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) Working limits: Pressure: ≤2MPa (single-layer bellows) ≤6.9 MPa (double-layer bellows) Speed: ≤25 m/s Temperature: -75ºC ~ + 425ºC Mechanical seal for Wilo pump, K, KM, X, AX, AXP, AX, Calpeda, DAB, Ebara, Grundfos, for KSB pump, Allweiler, SALMSON, ACD Cryo, Flygt, IMP Pumps, LOWARA, PENTAX, Foras, Fristam, for SPERONI pump, ZENIT, Inoxpa, JL, Johnson pump, KOLMEKS, Pedrollo, SAER, Vulcan, WQ, WQK, for Tuchenhagen pump, ALFA LAVAL, Donjoy, Mission Magnum.
