MECHANICAL SEALS FROM LLC “KB “UKRSPETSMASH” THAT ARE DESIGNED FOR REFINING AND CRUDE BOOSTER PUMPS

Pump BB4: single mechanical seals of ТМП make equipped with the hydrocyclone separator (Plan 31 according to API 682); there is an opportunity of washing (steaming) of the chamber with springs being in it.

Crude Booster Pump BB1: single mechanical seals of ТМП make with hydrocyclone separator (Plan 31 according to API 682); there is an opportunity of washing (steaming) of the chamber with springs being in it.

Semisubmersible Vertical Pumps for Pumping out of Leakage VS4: single mechanical seals of ТМД make equipped with the hydrocyclone separator (Plan 31 according to API 682);there is an opportunity of washing (steaming) of the chamber with springs being in it.

Semisubmersible Vertical Pumps VS4 : double mechanical seals of 2ТМ make equipped with the TS vessel (Plan 53А according to API 682).

MAIN TECHNICAL CHARACTERISTICS

  • Diameters of the sealed shafts: up to 150 mm
  • Maximum sealing pressure: during standstill is up to 12.0 МPа, in rotation mode is up to 6.5 МPа
  • Rotational speed of the shaft, rpm: up to 3 600
  • temperature of sealed fluid: up to 80 оС

MATERIALS USED

  • hot-pressed silicone carbide, silicone carbide, silicified graphite
  • compounded rubber based on FKM
  • stainless steels of grades304, 304L, 316, 316L

DESIGN FEATURES

  • cartridge design: ease at mounting/dismounting, it is not necessary in machining of pump parts
  • ease at assembling/disassembling: medium experienced personnel may perform these operations without special tools and appurtenances
  • friction pairs hydraulically balanced, spring are located outside of sealed medium, strong tappet elements, mechanical seals parts are resistant to thermal distortion and to distortion occurs due to applied loads
  • secondary seal: self-aligning throttle bush
  • their operating life is significantly higher than analogous mechanical seals have
  • mechanical seals are hydrostatically tested at the test-bench prior to being delivered
