Auras
Effectively pump out water with residues
Rund um die Uhr befreien Filter die verschiedenen Beckenkreisläufe des WaldSchwimmbads Neu-Isenburg in Hessen von Verunreinigungen. Um einen reibungslosen Badebetrieb zu gewährleisten, müssen auch die Filter täglich gereinigt werden. Hierbei vertrauen die Betreiber auf Technik des Frankfurter Pumpenherstellers AURAS und haben insgesamt zwei Tauchpumpen im Einsatz, die das durch Filterrückspülungen verbrauchte Wasser vom Schwimmbadkeller in den Abwasserkanal pumpen.
Im Hallenbad-Bereich des WaldSchwimmbads Neu-Isenburg reinigen bei laufendem Badebetrieb vier geschlossene Mehrschichtfilter das Wasser der Becken. Darüber hinaus ist eine Spülwasseraufbereitungsanlage mit Kies- und Aktivkohlefilter im Einsatz. Um das belastete Filterbett zu reinigen, werden täglich drei der vier Filter mit insgesamt 60 Kubikmeter Wasser rückgespült. Das verunreinigte Wasser gelangt dabei über die Spülwasseraufbereitungsanlage in den Pumpensumpf im Keller des Schwimmbads. 2017 installierten die Stadtwerke Neu-Isenburg in diesem Pumpensumpf zwei Tauchpumpen des Typs MAN 550/2/100 A1FT5 der ZETLINE-Serie von AURAS, die das verbrauchte Wasser in den Abwasserkanal pumpen. Den Höhenunterschied zum Kanal gleichen die Pumpen dabei problemlos aus.
Die Tauchpumpen laufen über eine Wechselvorrichtung, sodass sie immer abwechselnd im Einsatz sind. „Dadurch sorgen wir für die nötige Entlastung und sind zusätzlich für die Wassermassen im Falle eines Lecks oder Rohrbruchs gewappnet“, erklärt Denis Dörschung, Leiter des Bereichs Bäder & Sauna der Stadtwerke Neu-Isenburg.
Problemlose Förderung von Wasser mit großen Partikeln
Die MAN 550/2/100 A1FT5 der ZETLINE-Serie ist eine effiziente Elektromotorpumpe mit offenem Einkanal-Laufrad und einer maximalen Fördermenge von 36 Litern pro Sekunde. Große, freie Kugeldurchgänge für Partikelgrößen bis 50 Millimeter verringern die Verstopfungsgefahr durch starke Verschmutzungen im Wasser. Die Befestigung am Boden erfolgt über zwei Kupplungsfüße mit vertikalem Auslass, während ein Schiebeflansch mit Rohrführung das Ausbauen der Pumpen vereinfacht. „So entstehen keine langen Ausfallzeiten bei Wartungsarbeiten“, weiß Peter Schmidt, Mitglied der Geschäftsleitung bei AURAS. Das Tauchpumpen-Modell fördert problemlos nicht rechengereinigtes Schwarzwasser sowie Kanalisationsabwasser und eignet sich damit hervorragend für kommunale Hebeanlegen, Kläranlagen, Landwirtschaft und Industrie.

Freeing wastewater treatment plants from harmful sludge
To ensure optimum operation of wastewater treatment plants, primary and secondary clarifiers as well as digestion towers must be professionally cleaned on a regular basis and freed from harmful sludge. The Swabian company Industriewartung Süd offers an effective method for this and has been relying on the reliable and robust submersible pumps from AURAS in Frankfurt for years.
After a certain time, harmful sludge and debris settle in the primary and secondary clarifiers as well as digesters of wastewater treatment plants, which must be disposed of at regular intervals. Industriewartung Süd from Dormettingen in the Zollernalbkreis district specializes in sludge dewatering and disposal: With vehicles specially designed for this purpose and the submersible wastewater pumps from AURAS, the cleaning company can not only remove these sludges in a cost-effective and environmentally friendly manner, but also make them additionally transportable by extracting water.
“We work with the P 40 CS submersible wastewater pump from AURAS because it safely and reliably pumps wastewater containing particles up to 44 millimeters in size,” explains Sabrina Bethmann, Managing Director of Industriewartung Süd. The P 40 CS pumps the water-sludge mixture about 5 to 10 meters up from the clarifier or digestion tower and then 20 to 150 meters into a container. There, the debris is screened out and the residual water, freed from the sludge, is pumped back into the basin.
Robust and safe in operation
With its specially developed, robust and abrasion-resistant impeller, the powerful P 40 CS submersible sewage pump is particularly suitable for demanding drainage projects in municipalities and sewage treatment plants. “The pump weighs 62 kilograms and can be transported and used by one person with the practically shaped carrying handle and appropriate aids,” emphasizes Peter Schmidt, member of the management team at AURAS. Its motor is equipped as standard with a motor protection plug with on/off switch. A phase inverter and a signal lamp for rotating field control provide additional safety. Due to the side pump outlet, the P 40 CS is also easy to clean and designed to be relatively inexpensive and easy to maintain by skilled personnel. All individual parts are replaceable and available from stock.
Almost exclusively pumps from AURAS
Industriewartung Süd has been active in the industrial cleaning sector for more than 30 years and, with its approximately 60 employees, solves the most difficult cleaning problems for machines and systems on a daily basis. In doing so, it avoids chemical cleaning methods and solvents wherever possible. AURAS Pumpen has been a partner of the cleaning company for many years and provides an important part of the equipment. With forty pumps, Industriewartung Süd uses almost exclusively pumps from AURAS, of which around twenty are P 40 CS.

For demanding drainage projects
The P 40 CS submersible sewage pump from AURAS is specially designed for pumping sewage with a high proportion of solids, sludge, dirt or sand. A good ratio of weight and performance as well as the robust and high-quality construction make the P 40 CS a universal and reliable partner for construction companies, municipalities and sewage treatment plants.
With its specially developed, robust and abrasion-resistant impeller, the powerful P 40 CS submersible sewage pump from AURAS is particularly suitable for demanding dewatering projects in municipalities and sewage treatment plants. “The pump weighs 62 kilograms and can be transported and used by one person with the conveniently shaped carrying handle and appropriate tools,” emphasizes Peter Schmidt, member of the management team at AURAS. As a sewage, sludge or construction site pump, it safely and reliably conveys wastewater with particles up to 44 millimeters in size.
Long service life thanks to high-quality materials
The impeller made of chrome steel, the pump housing made of silumin, the diffuser made of abrasion-resistant rubber, the strainer, the base plate and the screws made of stainless steel – AURAS uses only high-quality materials for the production of its submersible sewage and wastewater pumps. “This is the only way we can guarantee a long service life and low downtimes,” knows Peter Schmidt. The motor of the P 40 CS is equipped with a motor protection plug with on/off switch as standard. A phase inverter and a signal lamp for rotating field control provide additional safety. Due to the side pump outlet, the P 40 CS is also easy to clean.
Like all other pumps from AURAS, the P 40 CS is designed to be relatively inexpensive and easy to maintain by qualified personnel. For example, various functions of the pump can be checked quickly and easily by means of an oil drain plug. All individual parts are replaceable and available from stock.
