Using a hydroshield, two 2.3km tunnels with diameter 6.78m will be constructed.During building works the lowering of the groundwater level must be assured.
Multiple submersible pumps from the KTV and KTZ series. The special characteristics of Tsurumi pumps, such as an internal mechanical seal, upstream shaft sleeve with gasket and a patented oil lifter allow them to be used in on-snore-mode over an extended period.
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.
