KSB opimized mechanical seal for waste water pumps

Friday, July 15th, 2016 von admin

The new double mechanical seal in tandem arrangement is especially well suited to the particular requirements of dry-installed and wet-installed waste water pumps. During development of the 4STQ – a double mechanical seal module – KSB’s engineers strove to ensure that its installation and removal remained as straightforward as possible. Assembly fixtures and fastening bolts are not required, and the seal’s modular design minimises downtime during maintenance inspections as well as preventing faulty reassembly.

EagleBurgmann: New mechanical seal for chemical pumps

Wednesday, September 9th, 2015 von admin

PM EagleBurgmann HRCNWith the HRC N mechanical seal series, EagleBurgmann provides a seal system (version DIN 24960, Part C) for standard chemical pumps with conically opened sealed space that complies with the requirements for a standardized and application-related seal solution.

As a novelty within the HRC… N series, EagleBurgmann has now launched the optimized double seal HRC3300N on the market that has the same mounting dimensions and which uses some of the non-variable parts from the predecessor HRC3000N. A new stationary seat that does not require binding was used. This, and the improvements to the seal on the atmosphere side, makes the HRC3300N definitely more service friendly. Omitting the binding makes it possible to use the high-performance DiamondFace diamond coating, and the operating temperature increases to +200°C (+392°F). (more…)

EagleBurgmann: Tried and tested 500,000-fold

Saturday, August 15th, 2015 von admin

Cartex 500 000 DFEagleBurgmann Cartex cartridge mechanical seals are completely pre-assembled and exactly positioned component seals with lid and shaft sleeve. They are fitted in the pumps of many industrial sectors, such as e.g. in chemistry, in water applications, in the food industry and in many other applications. More than 500,000 seals have been installed in the meantime and have proven their reliability and economic efficiency.

EagleBurgmann: Seal concept for light vaporous media

Friday, August 7th, 2015 von admin

PM_DF-P-DGS6With the DF(P)DGS6 EagleBurgmann offers reliable shaft sealing for API 610 high-performance pumps, e.g. BB3 and BB4 process pumps, and vertical pumps applied in liquefied gas fractionation, in pump stations of downstream NGL (Natural Gas Liquids) pipelines and also in CO2 applications.

Numerous plant operators experience problems incurred by temperature and pressure fluctuations in the pump. In conjunction with the low vapor pressure margin of the medium (e.g. ethane, propane), this can cause phase transitions between liquid and gas at the seal faces – they run dry. Conventional mechanical seals consequently sustain damages which results in seal failures.

Mechanical Seal Primary Rings for Sealing Refrigerants and Low Viscosity Liquids

Tuesday, September 17th, 2013 von admin

OLYMPUS DIGITAL CAMERALow viscosity liquids are difficult for mechanical seals because the hydrodynamic film that they create between the two rubbing seal faces is extremely thin. In order for this extremely thin hydrodynamic film to lubricate the two sealing faces, the seal faces must stay highly polished and they must run in very close proximity to each other. The self-polishing characteristic of  mechanical seals with antimony impregnated, carbon-graphite primary rings and solid silicon carbide counter face rings can solve this problem. Low viscosity liquids such as Freon refrigerants, liquid oxygen, liquid carbon dioxide, propane, ethylene, and acetone are now being successfully sealed using mechanical seals with Metcar Grade M-444, antimony impregnated, carbon-graphite primary seal rings.

Change in EagleBurgmann General Management

Friday, January 11th, 2013 von admin

On January 1, 2013, Michael Stomberg (42), the previous Senior Vice President and Head of Division Mechanical Seals, became the successor to Dr. Walter Steinbach who retired from the company on December 31, 2012. Michael Stomberg (COO) is now one of three General Managers and a member of the EagleBurgmann Executive Board (TMT).  Steinbach (61) had been a member of the general management since 1993, and until the end of 2012 he was responsible for different product divisions and intra-divisional topics, such as innovation management (products and processes), Supply Chain Management, or strategic projects.

Cartridge seal with benefits of high-performance technology

Tuesday, July 10th, 2012 von admin

eCartex

With the new eCartex, EagleBurgmann offers a combination of the

  • Cartex cartridge unit, proven by decades of use,
  • and the innovative DiamondFace (DF) coating,

especially characterized by its high dry-run capability and solids resistance. The eCartex utilizes DF-coated seal faces that stand for extreme hardness, resistance to wear, and excellent thermal conductivity. The result is a high savings potential that pays off quickly: Energy consumption is reduced by up to 80%.

High-pressure twin-screw pumps for food and beverage

Thursday, February 2nd, 2012 von admin

In many areas of the food and beverages industry there is a distinct trend towards the use of pumps that are able to reliably manage higher pressure differentials. This trend is due not only to the higher friction losses caused by longer pipelines and increasing flow rates in the production plants but also to the pumping of generally higher-viscosity media that enable savings in terms of energy to heat the media.
