MUCEM, Marseille, France

The Project:

New construction of the MUCEM (Museum of European and Mediterranean Civilizations) in Marseille, France, on an area of 26,000 m3.

Company involved:

Messrs. Dumez Mediterranée (VINCI Group)

Construction Manager: Mr. Francis Berny

The Problem:

The site is located in the immediate vicinity of the Mediterranean coast and the Old Harbour of Marseille. In the first construction phase, a square pit was excavated, with an edge length of 72 m. From a depth of 6 m seawater began to infiltrate, and flooded the excavation.

The Solution:

In the first phase, dirty water pumps were used, of the types KTZ31.5, KTZ21.5 and KRS2-80. Settling basins were then installed, each with a pump of the type KTZ33.7, with plastic piping and switchboxes.

The KTZ pumps will be running until the site has been completed, and the settling basin allows for the continuous purification of the dirty water.

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.
