Bibra Tunnel, Germany

The Project:


The Bibra Tunnel is part of the German Unity construction project No. 8, the extension stretch on the route Nuremberg-Erfurt-Leipzig-Halle- Berlin.


Company involved:

Marti Tunnelbau Bunte


The Problem:


Maintaining water clearance by means of submersible pumps at the tunnel portals and during the tunnel advance.


The Solution:


Use of Tsurumi dirty water submersible pumps of widely differing types to remove water from the tunnel. Thanks to their tough, robust design, and the special internally-located slide-ring seal, Tsurumi pumps can be kept permanently in operation in "on-snore-mode".

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.
