The multi spring design make sure the load on the seal faces are balanced. The top of the seal has radial bearing which can decrease the unnecessary movement of the shaft. The seal tank has cooling jacket that optimizes the operating conditions of the seal. The locked screw transmission design has directivity and it is easy to install with reliable performance.1. The top bearing should not be used as agitating support point.2. When the medium temperature is above 180 ºC a cooling tank is needed to be installed, which will increase the operating height of the whole component by 80 mm.3. When the pressure is above 0.3 MPa, auxiliary seal system is needed.Industrial Standards:HG5-754-78, HG/T2098-91, HG/T2098-2011Scopes of Application:widely used in chemical engineering, smelting, pharmacy, food processing, MHW, and oil refining. It is specifically designed for reactors, drying machine and evaporators.Operation Parameters:Pressure: - 0.1 to 2.5 MPaTemperature: - 40 ºC to 180 ºCLinear Speed: 2 m/s or lessMaterials:Rotary Ring Face: Surfacing Alloy/TC/SiCStationary Ring Face: Carbon/SiCElastomers: FKM/PTFE/EPDMSprings: SS304/SS316/HC276metal Parts: SS304/SS316/SS316L/2205/2507/Q235Mediums:water, oil, weak acid, weak alkali, flammable, explosive, toxic gas and etc.Customization:Changes of materials for getting other operating parameters are possible.
