Sealing critical gases without compromise

Ethylene and Propylene, are separated and supplied to the petrochemical industry. The gas mixture largely consists of methane, propane, butane and hydrogen. As it is contaminated with various substances, the gas is cleaned in scrubbers and is often used for heating.

Demands are high: Extreme temperatures, high speeds and pressures, combined with flammability and the risks that the gases pose to the environment demand uncompromising technology and sealing.

Our robust DGS and PDGS compressor seals have established their position as the default solution in the field of gas-lubricated mechanical seals for critical gases such as oxygen, hydrogen or carbon dioxide.
