Technical Relieve Organisation (THW) local association Cologne East
August, 19 - 31: First trial for the Tsurumi pumps at the rivers Elbe, Sieg and Rhine (Germany)
Shortly prior to leaving for fighting the century flood at the river Elbe, the local association Cologne East was able to procure two Tsurumi pumps within as short a period as 24 h, while the purchase was planned since November 2001. On receipt of the order on Friday noon at Tsurumi’s, the two electrical submersible pumps KRS-63 (200 l/min at a delivery head of 5 m, and 3,5 kW input power) were transported from the import warehouse in Antwerp to Düsseldorf, provided there with Storz couplings and protective motor switches, and - Saturday, shortly before 8 o’clock in the morning, Stefan Himmelsbach, sales manager with Tsurumi Germany, personally brought the pumps to the local association. In the area of service, Stendal, THW received the pleasant notice that Messrs. Tsurumi provided another four electrical submersible pumps type KRS2-100 (1500 l/min at a delivery head of 10 m and 6,9 kW input power with agitator, specifically to delivery sludge, silt and bentonit), which were to be supplied to the place of service as soon as possible.
August 24 - 26: Century flood at the river Elbe The pumps passed their first trial in Magdeburg. The horse racecourse Herrenkrug was flooded after a dyke blow and the water collected there penetrated the basements of neighbouring buildings. Over night the pump team consisting of helpers of the Cologne East and Cologne North West local associations and the Magdeburg town works were able to considerably lower the water level and to pass the water back to the sinking Elbe.
Typical “conditions of work” for submersible pumps during THW services: Dirty sludge water, delivering in semi horizontal position and in on-snore-mode – this requires really sturdy pumps
In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve and oil ring. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period. In this regard, please pay attention to our general conditions of sales (www.tsurumi-europe.com/english/GCS.htm) that we also send to you by mail on request.
