Mechanical seals and packings for sprinkler system of automobile manufacturer

Magna Steyr is an Austrian automobile manufacturer with a large production location in Graz. A sprinkler system is installed throughout the entire production plant which, in emergencies, can prevent a fire from spreading. This system uses diverse pump types which are sealed with EagleBurgmann Cartex cartridge seals (see picture), MG elastomer bellows seals, M2 and M3 component seals or with packings. Ruggedness is a requirement for all components when the availability of use of the system is tested on a regular basis. In this process, the pumps are operated with closed gate valves up to their workload limit.

Mechanical seals for water treatment in hospitals

Grundfos BioBooster A/S develops and distributes a new generation of compact, decentralized and modular sewage treatment plants, e.g. for water treatment of hospitals (shown here the system of the hospital at Herlev, Denmark), among others. These plants run maintenance-free in continuous operation. Their central components are new types of BioBooster filter units, each of which contain three EagleBurgmann MG1 shafts seals. They effectively prevent contaminated water from leaking into clean water.

EagleBurgmann MG1 in operation in bathing water circulation pumps

The UNIBAD bathing water circulating pumps with integrated hair and fiber filter, from the German pump manufacturer Herborner Pumpentechnik, are deployed in bathing complexes, water entertainment areas, and theme parks. The pumps are sealed with EagleBurgmann MG1 single elastomer bellows seals made of non-wearing materials.

Operating conditions: Temperature: t … 40 °C (104 °F), pressure: p = 4 bar (58 PSI), rotational speed: … 1,800 min^-1.

EagleBurgmann BT mechanical seals for swimming pool pumps

Speck BADU 90/15 pumps have been among the most successful swimming pool pumps on the market for decades. A reliable shaft seal plays a significant part in that. Type BT-AR EagleBurgmann BT elastomer bellows seals are installed in the BADU series after they had been qualified in extensive practical tests on the systems of the pump manufacturer in Neunkirchen/Germany.

Operating conditions: Shaft diameter: 20 mm (0.79"), temperature range: t = +28 °C … +38 °C (+82 °F … +100 °F), pressure: p = 0.8 bar (11 PSI), flow rate: 15 m³/h, rotational speed: n = 2,850 min^-1.

Toilet vacuum systems with elastomer bellows seals for ships and offshore installations

The Norwegian manufacturer Jets Vacuum A/S supplies toilet vacuum systems for different applications, such as for ships and offshore installations. The Vacuumarator pumps are installed directly in the line network. They generate a continuous vacuum which makes the system independent from exterior influences and pumps gray water and solids to the wastewater cleaning station. EagleBurgmann supplies specially designed MG97 elastomer bellows seals for the first fit of these vacuum pumps.
