Vinterbro tunnel, Norway

The project:

Tunnel on the E6 South section between Vinterbro and Assurtjen, 3.605 m in length

Executing companies:

Mika AS

Intec Pumper AS

The problem:

With a falling road grade in the tunnel, the water runoff from the mountain had to be pumped upwards over longer distances.

Our solution:

Use of multiple module KTV and LH pumps. Particularly the LH series provides the conveyor pressure needed to overcome the distances between the intermediate basins.

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.
