Renovation of underground parking garage, Munchich, Germany

The project:

Renovation of an underground parking garage built in 1971 in downtown Munich

Executing company:

Hangsicherung u. Sanierungs GmbH&Co.KG

The problem:

Renovation of an area of 4000m2, construction time 12 months. Removal of concrete surface with high-pressure equipment at up to 3000 bar water pressure. Draining water jets (up to 240 liters/min) with a high mud load must be pumped away.

Our solution:

The incoming muddy water is pumped out with a total of ten model LCS1.4S pumps. These are abrasion-resistant residual water pumps, which pump out the water down to a height of 1mm. The built in check valve allows continuous suction operation; no personnel is needed to monitor the pump operation.

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.
