TMR series single mechanical seals for agitators

Application of the mechanical seals for agitators

TMR series single mechanical seals are designed for sealing the rotating shafts of the agitators, reactors and other equipment, working with non-aggressive, non-explosive and non-fire-hazardous fluids, the leakages of which are acceptable into the atmosphere with due account of safety requirements.

Antifriction bearings are applied in the mechanical seal of TMR-P type in order to stabilize and reduce the radial runout in the seal.

The following piping layout is used to ensure a proper operation of the TMP and TMR-P series mechanical seals in the agitators: the flushing fluid is supplied from the external source into the cavity behind the friction pair.

Applications, as well as mounting and overall dimensions conform to T2 series mechanical seals according to ОСТ 26-01-1243-81.

Specific design features:

  • construction simplicity and reliability;
  • long service life in comparison with the similar ones;
  • the springs are removed from the sealed area;
  • the friction pairs are hydraulically unloaded;
  • cartridge type construction (simple installation / removal);
  • the auxiliary seal is a non-metallic throttle bush;
  • prior to shipment all mechanical seals, designed for agitators, are subjected to bed tests.

Mechanical seals, designed for agitators, which are used in the chemical industries, can be applied together with the following pumps:

  • large-capacity ammonia production pumps (condensate extraction pumps (items 112J, 113J, etc.), ammonia pumps (items 109J and 1002J), pumps and hydraulic turbine, working with the Carsol and Benfield solutions (items 106J, 107J and 107JHT);
  • ХБ 160/210 and ХБ 500/260 series ammonia water pumps;
  • MSD 8х10х15 and MSD 4х6х10 series ammonia main line pumps;
  • Х 45/31 ГОУ series graphite pumps.

Parameters in the seal working area

  • Sealing pressure: up to 35 atmospheres;
  • Temperature of the sealing liquid / gas: from minus 30 up to 200 °С;
  • Temperature during the operation between the casing of the chemical device and thermal barrier (cooler on the shaft): up to 400 °С.

Applicable materials:

  • silicium carbide, tungsten carbide, silicified graphite and antifriction carbon graphite;
  • rubber compounds based on fluorine rubber, perfluoro elastomer and ethylene propylene;
  • stainless steel of the grades 20X13, 08Х18Н10Т, 10Х17Н13М2Т and 06ХН28МДТ.
