Buchrain Tunnel Consortium, Switzerland

The project:

Construction of a road tunnel as part of the Rontal motorway feeder road

Executing companies:

ARGE Tunnel Buchrain

RL Pumpenanlagen GmbH, Bilten

The problem:

Provision of treated non-drinking water for the entire site; water intake from a nearby stream.

Our solution:

A KTZ33.7 pump is used to pump the untreated water out of the stream through a cyclone filter and into the water reservoir. The cyclone filter is used to separate off solids. The non-drinking water is supplied to the site via a pressure booster system.

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.
