Sealing solutions for deep-sea extraction

Deep-sea conveying equipment on the sea floor currently extracts oil at depths down to 3,000 meters. This oil is then pumped directly onto ships or on land via underwater pipelines.

High pressures, low temperatures and the fluctuating composition of the media pumped characterize the conditions for sealing systems in multiphase pumps. Since recovering and repairing lowered pump units is extremely expensive, the seals also have to ensure maximum failsafe protection and extended maintenance intervals. Pressurized dual mechanical seals are typically used here.
