Single face seals ТМ, ТМП, ТМХ
Single face seals ТМ, ТМП, ТМХ
Single end sealing brands ТМ, ТМП, ТМХ — to be used in non-aggressive, non-explosive, firesafe liquids, leakage of which in atmosphere is permissible considering security requirements.
Sealing type TM, TMP, TMX
Pumped medium temperature, °C from –30 to +100 ºС
to +400 ºС
Piping as in API 682 Plan 01, 02, 11, 12, 13, 21, 22, 31, 32, 41
Can be used in pumps of the following brands NK, NKV, NPS, CNS, CN, PE, SE, D.

Single face seals ТМ, ТМП, ТМХ are designed for use with non-aggressive fluids, non-explosive/non-flammable fluids with atmospheric release allowed with due regard to safety requirements. ТМ and ТМП seals (with secondary seal by means of a slotted bush inside the body) can be used with water, aqueous salt, acid and alkaline solutions, cold oil, and cold oil products (with temperatures below 80 °С). The fluids should have good lubricating properties and should be reasonably clean (not more than 0.2 % of solid impurities). If the fluid contains abrasive solid particles, underflow seals are used. ТМХ face seals (with built-in shaft cooler) are designed for use in hot media with temperatures before 400 °С.
