Fraport AG storage container, Frankfurt, Germany

The project:

Construction of storage container for a wastewater treatment plant at the airport.


Executing company:

Heitkamp Ingenieur- und Kraftwerksbau GmbH


Tsurumi dealer:

Biergans Pumpen Vertrieb GmbH, Duisburg


Tsurumi consultants:

Mr. Stefan Himmelsbach (Product Manager Construction Pumps)


The problem:

Quick, problem-free filling of three silos with a volume of 10,000m3 each with water to test for leaks. The three silos, each 23m high, are part of the southern wastewater treatment plant of the Frankfurt Airport.


The solution:

Use of a model KRS822 immersion pump. The pump is set up dry and operated in a horizontal position. A carrying frame makes the pump transportable. The special characteristics of the pump, such as an internal mechanical seal, upstream shaft sleeve with gasket and a patented oil lifter, allow it to be operated dry in a horizontal position.

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, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. 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 terms and conditions that we also send to you by mail on request.
