Mechanical Seal for Pump

The pump mechanical seal are installations that perform dynamic sealing operations in pump installations, it is a kind of component that avoids the flow of fluid medium through the pump shaft through the pump shaft.

It is different from the mechanical seal of the cauldron, the sealing medium of pump mechanical seal is mostly liquid, solid liquid mixture and atmospheric pressure. Because the pump is mostly conveying fluid medium, it has the characteristics of horizontal installation, high speed, high pressure, solid particles and corrosive characteristics. Therefore, the mechanical seal of the pump is usually required to resist the erosion of solid particles and the high speed of the sealing surface, the influence of the high pressure on the parameters of the sealing parameters and the corrosion of the matrix structure. The mechanical seal material usually requires high sealing surface friction material with optional nickel base alloy, cobalt based alloy, silicon carbide, pressureless sintering and reaction sintering silicon carbide metal impregnated graphite, graphite filled PTFE, PTFE filled with glass fiber, three special two aluminum oxide ceramics and so on; 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, PTFE and so on; The optional materials for spring compensation are HHS, 1Cr18Ni9Ti, 3Cr13, etc.

The mechanical seal of pump is one of the most precise and complicated mechanical basic components, which is the key part of pump machinery. Its sealing performance and service life depend on many factors, such as selection, precision of machine, correct installation and use. There are many kinds of mechanical seals for pumps. Models vary, and its maintenance is difficult to discern and judge.
