Seals are a risk factor in the production of liquid crystals. If there is even the slightest contamination of the liquid crystals, this will later affect the image quality of the display. Read on to see which sealing solution Merck KGaA uses in paddle dryers for the production of liquid crystals.

They are often overlooked but play a crucial role when it comes to sustainability: modern and complex sealing solutions. Digital technologies now enable remote  monitoring, helping to increase their service life and therefore reduce their ecological footprint.

A major natural gas provider in North America was experiencing frequent dry gas seal failures on one of their pipeline compressors. This interrupted gas transportation, causing challenges to meet customer demands, along with unplanned and costly maintenance.

The Etzel oil and gas cavern system is situated southwest of Wilhelmshaven, not far from the North Sea coast. A vast salt dome houses the more than 70 caverns which store crude oil and natural gas at depths between 900 and 1,700 meters. Etzel is integrated in the northwest European oil and gas pipeline network and makes a significant contribution to the safe and reliable supply of gas to Germany and all of Europe.

In Great Britain, a shortage in natural gas supply has severe consequences: Since the country switched from coal-fired to gas-fired power stations, a gas supply shortage makes households and industrial consumers not only vulnerable to failing heating and gas stoves, but also to power outages. Companies along the value and transportation chain of natural gas are therefore especially dependent on reliable equipment.

Special expansion joints from  EagleBurgmann compensate for these position changes and work reliably even under unfavorable conditions such as low temperatures, proximity to the sea and explosive environments. 

A boiler circulation pump in a power plant conveys very hot and pressurized water. The pump has no cooling jacket, which increases the risk of a thermosiphon effect.

Mechanical seals are not always the best choice. In roller dryers used in the production of pharmaceutical powder, abrupt shaft deflections during processing led to increased seal wear. Operation was maintenance-intensive and prone to faults.

The new zero-emission mechanical seal from EagleBurgmann prevents the emission of the greenhouse gas methane during natural gas extraction, transport and processing.

A chemicals company in the Middle East uses the refrigerant R134A-Freon in the production of toluene diisocyanate (TDI). Shortly after the refrigeration plant is commissioned, the seal of a magnetic coupling pump fails. Quick help was called for.

Our modern civilization is quite literally built upon cement. Today, building materials made from cement are used in buildings, roads, bridges, dams etc. Cement production is a heat-intensive process and causes thermal expansion in duct systems. To compensate this, Indian cement producer Ramco Cement needed fabric expansion joints with a diameter of several meters for two of their plants. On the basis of a close collaboration, EagleBurgmann was able to design components that increase the efficiency of the plant in the long run.

In the highly sensitive production of vaccines, only a few barrier media and materials are approved for mechanical seals. If steam condensate is to lubricate silicon carbide sealing surfaces, premature wear is inevitable. How it actually does work is demonstrated by the case of an internationally operating pharmaceutical company.

By means  of custom-made PLUG & RUN expansion joints  with a more wear-resistant material, EagleBurgmann was able to provide a solution which ideally fulfills the requirements with regard to wear while at the same time significantly reducing the changeover time.

Barrier fluid for seals is a risk factor in the pharmaceutical industry as it could contaminate the active ingredients produced. A globally active company is playing it safe and replacing liquid lubricated mechanical seals in paddle-wheel dryers with dry-running mechanical seals.

Between June 2017 and March 2019 the Hengli Group constructed an integrated refining and chemical complex in the Chinese harbor town Dalian where 20 million tons of crude oil are processed every year. EagleBurgmann advised the company Hengli concerning the selection of mechanical seals and supply systems for the whole plant and supplied more than 95 % of the components in use. 

The piston booster that an American compressor manufacturer had selected and qualified to include in its compressor package proved unreliable for supporting customer’s needs. These seal gas boosters led to maintenance issues with both the boosters and the dry gas seals. To deliver on their reliability claims, the OEM decided to include new, state-of-the-art technology in its offering.

Water scarcity is one of the core issues of our time. As a leading global enterprise for the provision of efficient and sustainable water cycle technologies, Xylem is committed to fighting water shortages through innovative and resourceconserving solutions.
