Water Caverns in Norway


Skanska, one of the largest construction groups in the world, was looking for reliable pumps for a water cavern project.


Tsurumi support
Dewatering layout support, consultations on site to improve installations.

The problem

Inside of the project the pumps were installed in remote places, hence if they failed, it would get complicated to get to the pumps for maintenance. Therefore, pumps with an outstanding lifetime were required.

The solution

Skanska had been using several Tsurumi products for a while already, hence the choice for a KTZ411 was esily done. According to the guys on site "The #Tsurumi pumps run and run!" pumps run and run!"

Specifications KTZ

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.
