M74-D механическое уплотнение

M74-D-type mechanical sealTwo-Face non-balanced rotation Multiple springsM74-D design performance, double-end structure applied to crystallize, easy to leak fiber media with particles. For low boiling, corrosion, toxic media, in particular, may double seal, work, should be sealed chamber cooling fluid, coolant pressure should be greater than the medium pressure.Structural features: Two-Face, rotation, meet EN12756 (DIN24960) standard, multi-spring split.Application: applies to crystallize, with particles, fibers and other media.Operating parameters: pressure: M74-D non-balancedLess than or equal 2.5MPa H74-D balanced ≤ 4.0MPaTemperature: -40 220 Degrees Celsius Speed:Less than or equal 20 m / sConstruction Material: Seals: graphite, silicon carbide, tungsten carbide, alumina Auxiliary Seal: Nitrile rubber, fluorine rubber, ethylene propylene rubber, PTFE Metal Components: Stainless steel
