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
