Intermediate access gallery, Stelzen, Germany

The project:


Construction of the Stelzen intermediate access gallery during the building of the Blessberg railway tunnel.


Executing company:

Alfred Kunz Untertagebau GmbH


The problem:


Tunnel drainage under difficult conditions: long adits with a minimum of available space.


The solution:


Type KTZ35.5 pumps were installed in the pipeline as booster pumps. This special solution can be easily implemented with any of our standard contractors' pumps.

Thanks to the simple construction and the inhouse developed oil lifter, Tsurumi contractors' pumps can run dry absolutely trouble-free. The minimal cooling due to the flowing medium is sufficient.

U slučaju abrazivnog i korozivnog korišćenja, u nekim komponentama može doći do prirodnog habanja. U pogledu gornje primene do habanja može doći pre svega kod rotora, agitatora, usisne ploče, rukavca vratila, uljanog prstena, mehaničke zaptivke, kućišta pumpe, sita, kućišta motora i ispusne spojnice. Radni vek ovih delova može znatno da varira zavisno od radnih uslova i može biti kraći od garantnog perioda.
U tom smislu obratite pažnju na naše opšte uslove korišćenja koje vam takođe na zahtev šaljemo poštom.
