(0)

LLC “KB “UKRSPETSMASH” offers mechanical seals for pumps designed for energy generating industry

Boiler Feed Water Pumps ПЭ, ПТ, ПД : single mechanical seals of ТМ make equipped with a thermal barrier and external heat exchanger

Condensate Pumps Кс, КсВ: single mechanical seals of ТМД make, barrier fluid is supplied from the external source; double mechanical seals of 2ТМ make; barrier fluid is supplied from the external source

Pumps СЭ: single mechanical seals of ТМ make equipped with the thermal barrier and external heat exchanger

Fuel-Oil Pumps НК : single mechanical seals of ТМП make and tandem mechanical seals of 2ТМТ make equipped with a hydrocyclone separator and reservoir

Circulating Pumps ЦН and Waste Heat Boiler Pumps НКУ : single mechanical seals with the thermal barrier

MAIN TECHNICAL CHARACTERISTICS OF MECHANICAL SEALS

  • diameters of the sealed shafts: from 40 to 150 mm

  • maximum sealing pressure: up to 12.0 МPа

  • rotational speed of the shaft, rpm: up to 10 000

  • temperature of sealed fluid: up to 300 оС

MATERIALS USED

  • silicone carbide, silicified graphite, antifriction carbon-graphite

  • compounded rubber based on ethylene-propylene copolymer, FKM

  • stainless steels: ANSI 304, 304L, 316, 316L

FEATURES OF DESIGN

  • cartridge type: ease at mounting/dismounting

  • ease at assembling/disassembling: medium experienced personnel may perform these operations without special tools and appurtenances

  • friction pairs hydraulically balanced, non-contacting, of pulse type

  • their operating life is significantly higher than analogous mechanical seals have

  • mechanical seals are hydrostatically tested at the test-bench prior to being delivered
