Nalazite se ovde:

NoordZuidLijn, Amsterdam, Netherlands

The Project:


Expansion of underground network in Amsterdam; construction of north-south line


Executing companies:

Max Bögl

ARGE Saturn (DuraVermeer and Züblin)

Distrimex b.v.


The problem:


The NordZuidLijn will be a new underground railline crossing Amsterdam from north to south.Amsterdam is situated at sea level, with many canals running through the city and historic sites that require protection. For these reasons, the lowering of the ground water during construction work must be carefully planned; this applies in particular during the building of the Rokin, Vijzelgracht and Ceintuurbaan stations in the city centre. Completion is expected to be in 2013.


The solution:


KTZ and KTV series pumps lower the groundwater during construction work on the underground stations and tunnels. Multiple pumps are kept on standby or are in mobile use.

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.
