The "Sedrun Section" of the Gotthard Basistunnel encompasses two tunnels that are each 6,2 kilometres long and supplied through a 800m deep mine shaft. Two tunnels are at the base of the shaft and each breaks through to the north and south in the conventional manner.

The project tunnels through the unstable rock of the Tavetscher Zwischenmassiv with an up to 2.000m overlay. One of the two multifunctional sections of the 57 km long Gotthardbasis Tunnel is also being built in the Sedrun section.


The problem:


Pumping off the abrasive water that collects during the tunnelling excavations.


Our solution:


Use of the current 80+ Tsurumi wastewater submersible pumps for complete drainage. Pump series used: KTZ, KRS, KTV, LH, KRS with agitator.

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.
