Argentina

Clean gas despite fluctuating operating conditions

Frequent starts and stops are a severe test for gas-lubricated compressor seals. Installed in an Argentinean combined cycle power plant is an EagleBurgmann supply system that provides a continuous gas flow rate for the seals and adapts it to changing conditions. Since then, the operational reliability of the compressors has increased significantly.

DF-M7N DiamondFace for tank drainage pumps

The chemical company Global Amines is one of the worldwide leading manufacturers of special chemicals. The "Southeast Bavarian Chemical Triangle", near Altötting, Germany is the location of the Gendorf plant. Global Amines produces preliminary, intermediate and finished chemical products here. EagleBurgmann successfully converted a chemical standard pump from a competitor's seal to an EagleBurgmann DF-M7N DiamondFace mechanical seal and achieved significantly increased pump and system availability.

High pressure compressor seal for Tupi 4

The Lula oil field off the coast of Brazil is considered one of the largest oil discoveries in recent years. It was brought into production using FPSO (Floating Production Storage and Offloading) platforms. EagleBurgmann supplied the GE compressors at the Tupi 4 floating production site with new and innovative ultra-high-pressure DGS for gas re-injection.
