Pump mechanical seal

Due to water pump for conveying fluid, with horizontal installation, high speed, high pressure, with solid particles, corrosion resistance and other characteristics, so the pumps with mechanical seal body material often need to resist the scour the impact of solid particles, high speed of sealing surface abrasion under high temperature, high pressure seal parameter is not stable, matrix structure corrosion, etc. The influence of unfavorable factors, higher requirements for mechanical seal sealing material, usually sealing surface friction pair optional material has nickel-based carbide, cobalt base reaction sintering cemented carbide, pressureless sintering of silicon carbide, silicon carbide, metal graphite, ptfe filler graphite, ptfe filled with glass fiber, 3 oxidation 2 aluminium special ceramics, etc.
The base material can be selected as 2Cr13 stainless iron, 301 stainless steel, 304 stainless steel, 316 stainless steel, 316L stainless steel, 904L stainless steel, polytetrafluoroethylene, etc.The spring compensator can be selected as the haji alloy, 1Cr18Ni9Ti, 3Cr13 and so on.
