Gas-lubricated cartridge seals

GK

d = 40 ... 160 mm p = 0.2 ÷ 2 MPa ; t < 170 °C ; v = 4.8 ÷ 15,5 m/s

Features

Double seal in "face to face" installation, compact design, balanced, dependent on direction of shaft rotation, multi-spring. Requires barrier gas supply.

Applications

The GK seals are designed mostly for process pumps used in refining and petrochemical industries, in chemical industry and coking plants, and in particular in pump installations with a high level of explosion risks and increased emissions of volatile substances into the environment.

The GK seal requires continuous supplying with filtered barrier gas (most commonly nitrogen) of pressure ~ 0.2 MPa higher than the sealed medium pressure.
