In the course of expanding the western railway, OBB Infrastruktur Bau AG is building a 42,3km long section of rail between Vienna and St. Pölten.

The approximately 13,35km long Wienerwald Tunnel comprises a significant part of this newly built section and connects the western edge of Vienna (Hadersdorf-Weidlingau) with Tullnerfeld.

The opening of the complete Wienerwald Tunnel as part of the newly built section between Vienna and St. Pölten is planned for 2012.

The problem:

Open drainage during tunnelling and construction in the open using submersible pumps.

Our solution:

Use of the following pump types: KTV2-22,

KTV2-37, KTZ22.2, KTZ32.2, KTZ45.5, KTZ47.5, LH25.5W

Advantages of Tsurumi pumps:

  • longer operating life
  • lower replacement parts costs
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.
