The Nassfeld ski resort in Carinthia, Austria relies on modern artificial snow technology in terms of snow guarantee. To that end, an extended system of pump stations and pipelines were installed in a number of expansion stages. In 2015, the manufacturer Lowara Vogel supplied four additional high pressure pumps, three volute casing pumps as booster pumps before the filters and one volute casing pump as medium pressure pump for the valley region. In sum, approx. 1,440 m³/h is pumped with up to 50 bar (725 PSI) from the reservoir to the system. The shaft seals in the high pressure sector are EagleBurgmann H75, the low pressure range uses EagleBurgmann MG12.
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.
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.
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.
