Danube power plant, Asten, Austria

The project:


Installation of a drain pump for the turbine inspection chamber.


Executing companies:

Verbund Austrian Hydro Power AG

Sonnek Engineering GmbH (Tsurumi partner)


The problem:


For inspection work the turbine must be completely drained at the intake and discharge including the headrace tunnel. New turbines are integrated in the collector shaft. Depending on the inspection cycle, the unfiltered water from the Danube must be pumped away there.

Pump requirement: 300m3/h at 3bar. Until now clean water submersible pumps were implemented which were always at risk of silting.


The solution:


Implementation of a type LH845 high-pressure pump with a 45kW rating. This conveys the existing pressure line at a pressure of 2.8bar 5m3/min.

Tsurumi contractors' pumps are perfectly suited for dirty media which means that they can also be operated after flooding (extreme silting).

I tilfælde af slibende og ætsende anvendelse vil stærkere slitage forekomme naturligt i visse komponenter. Med hensyn til ovenstående anvendelse kan slitage hovedsageligt finde sted i pumpehjul, omrørerenhed, sugeplade, akselhylster, oliering, mekanisk tætning, pumpehus, si, motorhus og udløbskobling. Afhængigt af arbejdsvilkårene kan levetiden for disse dele variere betydeligt og kan være kortere end den lovlige garantiperiode.
