To ensure high reliability of gas seals, a clean and dry gas at the seal is required. Gas supply systems draw product gas from a higher-pressure stage of the compressor during dynamic operation, filter the gas and use it for flushing the seal. In standstill operation of the compressor there is no gas source of higher pressure available due to the lack in flow in the machine, i.e. the seal cannot be protected from contaminated product gas.
DiamondFaces®, the microcrystalline diamond coating from EagleBurgmann, raises the reliability and performance of your mechanical seals several times over.
At the beginning of 2009 a contract between EagleBurgmann-Middle East and a major Middle Eastern oil refining company was signed in order to upgrade recycled gas compressor oil bushing seals to EagleBurgmann gas seals in the IsoMax unit.
Due to serious concerns of repeated oil seal problems, the customer decided to upgrade the old sealing system along with the next major overhaul set for October 2009.
In December 2009, EagleBurgmann China established a new Dry Gas Seal (DGS) Service Center in the EagleBurgmann Dalian factory in order to meet local Chinese customer and market requirements.
The opening of this new facility now offers the region's customers a local dedicated center of excellence that provides a static gas seal testing and repair facility. "As a result, customers will benefit from more rapid turnaround times, improved service and local access to the wealth of specialist sealing expertise that EagleBurgmann has at its disposal" said Simon Guo, CEO of EagleBurgmann China region.
EagleBurgmann’s newly developed double Cartex® GSDN gas seal is the ideal solution for centrifugal pump applications at chemical plants and refineries. Users can install bi-directional gas-lubricated Cartex® GSDN seals to standardize their new pumps or to recondition existing pumps which have conventional stuffing box packings or liquid-lubricated mechanical seals.
The APItex® series developed by EagleBurgmann includes single and double pusher type seals in cartridge design which are fully compliant with API 682 Category 1 Type A. These robust, reliable seals are designed to withstand process fluctuations and shaft deflection. The shrink-fitted seal faces and the floating seat mounting ensure dependable operation.
There is probably no other industry that has come under such intense scrutiny as the oil refining industry. Still, there is no denying that processing crude oil into useful petroleum products such as gasoline, diesel fuel and heating oil is an important part of the world’s economy. Furthermore, the oil refining industry has made substantial changes to be more environmentally friendly both in its product line and process facilities.
One of the by-products of clean fuel production is liquid molten sulfur. As environmental legislation mandates stricter controls on refined products, oil refineries must remove more sulfur from their refined products, such as diesel fuel. The recovered sulfur, sold to other industrial companies, finds use in other products such as fungicides, black gunpowder, detergents and phosphate fertilizers, and for rubber vulcanization.
EagleBurgmann has established the high performance SHF mechanical seal for use in multi-stage high-pressure boiler feed pumps in power stations.
This successful mechanical seal is notable for a low rate of wear, minimal leakage and high availability, even at high peripheral speeds. It is extremely long lasting even in peak load power stations with frequently fluctuating loads. Years of experience in the design and practical use of a multitude of high-pressure feed pumps come out in this mechanical seal.
The reliability of gas seals depends on an adequate flow of clean dry gas at the seal. Gas supply systems take product gas from a higher-pressure stage of the compressor, filter the gas and use it to flush the seal. When the compressor is not running, the flow is interrupted and there is no source of high-pressure gas to protect the seal from contaminated product gas. This can pose a serious risk, because deposits at the seal can cause leakage or even damage the seal. In order to alleviate this problem, piston compressors/boosters driven by compressed air have been deployed in recent years to suck in filtered gas from the compressor, increase the pressure and use the gas to flush the seal.
EagleBurgmann has launched a new separation seal offering a proven solution to the problems of oil penetrating from a compressor bearing into an outboard gas seal, and the ingress of process gas from the outboard stage of the gas seal into the bearing cavity. EagleBurgmann carbon ring seals and the new CobaSeals are designed primarily for turbomachinery applications and between them offer a choice to meet customer requirements for separation seals.

The manufacturing of chemical and pharmaceutical products puts considerable strain on the sealing technology utilized. Optimum quality, a worldwide service network and decades of experience in application engineering make EagleBurgmann a leading manufacturer of sealing systems in these industries.
In addition to meeting stringent technical requirements, a seal has to adhere to many other regulations in connection with cleanliness, health and government legislation. EagleBurgmann mechanical seals have been used successfully worldwide in sterile processes for over 20 years.
The cutter heads on quarrying and mining machining are fed with water, not only for cooling purposes but also for settling the dust and extinguishing any sparks produced by the cutting tools. EagleBurgmann mechanical seals perform the dual function of rotary joint and seal for the cutter and roller heads.
EagleBurgmann sealing systems feature maximum operational reliability, convenient maintenance and low leakage rates with necessary environmental protective measures.
