Single mechanical seal TM, TMP, TMX

Single mechanical seal TM, TMP, TMX - used in non-aggressive liquids, neutrino-flammable liquids drain into the atmosphere Pets with your safety in mind is usually to replace the seals brand BO. Seal TM and TDM (with auxiliary seal in the form of a slit in sleeve the housing can be used on water, aqueous solutions of salts, acids and alkalis, cold oil and cold oil (temperature not more than 80 deg C). Fluid should possess good lubricating ability and to be quite clean (up to 0.2% solids). If the liquid contains solid abrasive on, then seals are used with the hydrocyclone. Mechanical seal TMH (with built-in refrigerator on the shaft) is used only in hot environments temperature of + 200 deg C.

Tandem mechanical seals TMT and TMTH - used in the when single, you cannot apply a condition for the required level of safety (hot oil, flammable and toxic liquids and others). Tandem seal applies only on tank scheme 52 API 682 pure liquids (not more than 0.2% impurities) with good lubricating ability, because of internal friction pair works on the fluid and the external buffer liquid from the tank.
At temperatures up to + 200 deg C is the seal TMT with the tank.
At a temperature of from + 200 to + 400 deg seal is used with TMTH a tank.
Tandem mechanical seals TMT and TMD installed instead of the tandem mechanical seals brand NAM...M, USG, UTT, utth, etc.

Double mechanical seal TM and TMX - used in when getting pumped product into the atmosphere unacceptable (poisonous, radioactive, explosive liquids and gases), also, if the pumped product has poor lubricity (gases, liquefied gases) or the pumped product is highly contaminated abrasive inclusions (up to 25%) or has a tendency to coking, polymerization, crystallization, etc.
Double mechanical seals are used only with the barrier fluid pressure which is higher than that of the sealed 1...3 kgf/cm2 (API plan 53 and 54). Both pairs friction work on the barrier liquid, part of which falls within the pumped product, and part of the atmosphere.
At temperatures up to + 200°C is used, the mechanical seal 2TM type with tank (API plan 53) or with the supply of barrier fluid from an external source (API plan 54).
At a temperature of from + 200 to + 400°C seal is used TMH (API plan 53 and 54).
Double mechanical seal TM installed instead of double mechanical seals brand DK, DNA, databases, and other UTD
Double mechanical seal TMH installed instead of double mechanical seals brand DNT, and other UTAH
