2tmt-big

Mechanical Seals of 2TMT Make – are intended for sealing of shafts of centrifugal machines that operate with gases and fluids, which have no corrosion action on mechanical seal parts, and leakage of which is inadmissible to the environment in pure state according to reference documents. They are necessary when it is prohibited to install single mechanical seals due to required security level (hot oil, high inflammable and toxic fluids, etc.)

Mechanical Seals of 2TMT Make– contain the thermal barrier are designed for pumps that operate with liquids, temperature of which exceeds 200 °С

DESIGN FEATURES

  • mechanical seals of cartridge type that are easy at mounting/dismounting
  • spring are located outside of sealed medium
  • friction pair seal rings are hydraulically balanced
  • secondary seal are non-metallic throttle bushes
  • to be used with the reservoir as per Plan 52 according to API 682

MATERIALS USED

  • silicone carbide, tungsten carbide, silicified graphite, antifriction carbon-graphite
  • compounded rubber based on FKM, FFKM, EPDM
  • stainless steels 304, 304L, 316, 316L

MAIN CHARACTERISTICS OF MECHANICAL SEALS

Temperature of sealed medium, °С from -30 to 200*
Pressure of product in the seal chamber, МPа up to 3,5
Temperature of buffer fluid, °С from 30 to 80
Rotational speed of the pump shaft, rpm up to 3600
*For mechanical seals 2ТМТХ is up to 400 °С
