Shaft seal in air separation compressor
In an air separation plant in Austria, the compressor for production technical gases is sealed by a gas-lubricated DGS20 mechanical seal.
Operating conditions: p = 7 … 30 bar (102 ... 435 PSI), t = 40 … 70 °C (104 ... 158 °F), n = 10,000 … 20,250 min-1.
Shaft sealing for gaseous media
Gas-lubricated MFLC-GS metal bellows seals as single or double seals for the shafts of process pumps in air separation plants. Typical process media are liquefied gases such as nitrogen. The low temperatures require special materials for the secondary seals, such as the proven Statotherm graphite seals.
Operating conditions: p = … 25 bar (363 PSI), t = … -199 °C (-326 °F), n = 6,000 … 8,000 min-1.
Metal bellows seal for tank pumps
Sealing of tank loading and unloading pumps with MFLS12 metal bellows seal. The low temperatures demand the application of special seal face and secondary sealing materials with BAM approval.
Typical operating conditions: p = 5 bar (73 PSI), t = -190 °C (-310 °F), n = 6,000 … 8,000 min-1.
