As a technology driven company, TISTAM constantly applying the latest technology in the mechanical seal Manufacturing, especially high-parameter pump seal technology has achieved a breakthrough, such as high-speed dry gas face seal occasion, hot hydrodynamic wedge mechanical face high pressure or high temperature applications sealing has been obtained in the petroleum, petrochemical, chemical, nuclear and aerospace fields applied successfully, but the known parameters of the shaft end is sealed with high mechanical face, there are still some deficiencies.
The 551® mechanical seal patentscope certification WO/2007/009470 multi springs depends on self internal sliding between wedge pure graphite ring and mechanical seal’s neck, the hydraulically balanced calculated in design to application in pressure up to 40 bar. end seal ring packing fixed and pressed to processing in static hydraulic, The approximate length of 551 m. seal is taller than another similar that useful to installation of 551 and it prevents best results.
The invention used in difficult application high pressure up to 40 bar and high temperature up to 500 °C and high velocity in industrial petroleum refinery and chemicals.
