SpecificationsGinseal PTFE Graphite Packing with OilGINSEAL PTFE packing is used in high purity and corrosion resistance is required; It is widely used in food industries, the pharmaceutical industry. GINSEAL PTFE packing has four types as follows:PTFE Graphited PackingItem no.: JSP-PT40 PTFE Graphited Packing is is soft, with low density There are no free particles of graphite on surface and therefore no contamination can occur. Operating rangePressure:p(pumps) = 25 bar, p(valves) = 100 bar,p(plunger pumps) = 250 bar,p(mixers, agitators, kneaders, filters) = 25 barSliding velocity:vg(pumps) = 12m/s, vg(valves) = 2 m/s,vg(plunger pumps) = 2 m/s ,vg(mixers, agitators, kneaders, filters) = 2 m/sTemperature: t = -75 °C ... +280 °C, hot water, without cooling system:max. +140 °CChemical resistance: pH = 0 ... 14
