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.

U slučaju abrazivnih i korozivnih primjena, normalno je da će se u određenim komponentama dogoditi snažnije trošenje. S obzirom na gornju primjenu trošenje se može odvijati uglavnom u radnom kolu, miješalici, usisnoj ploči, rukavcu osovine, uljnom prstenu, mehaničkoj brtvi, kućištu pumpe, cjedilu, kućištu motora i ispusnoj spojki. Ovisno o radnim uvjetima vijek trajanja tih dijelova može značajno varirati i može biti kraći od pravnog zakonskog razdoblja.
