The dimensions of the 40GK/GN seal are shown above. Seals GK/GN in other sizes are shown in the configurator and catalogue card, available at the top of the page.
General characteristics
Double seal in “face to face” installation, compact design, balanced, dependent on direction of shaft rotation, multi-spring. Requires barrier gas supply.
Range of sizes available
- Shaft diameter: d = 40 ... 160 mm
Operating parameters
- Pressure: 0.2 ÷ 2 MPa
- Temperature: < 170 °C
- Velocity: 4.8 ÷ 15,5 m/s
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.
