Cemex Concrete Plant, Gilching, Germany

The project:

Use of submersible pumps at the Concrete Plant Gilching


Company carrying out the works:

Cemex AG


Tsurumi supervisor:

Mr. Christian Kulik (Field Sales Team Bavaria)


The problem:

Transport of dirty water from the washing facility for concrete mixers. These contain abrasive concrete sludge.


The solution:

Use of highly wear-resistant type HS2.75S (230 V, 750 W) pumps. Fitted with an inside, double floating-ring seal in an oil bath, protected by a shaft protection ring and upstream sealing ring, this pump is suitable for dry running and dragging operations. Solids up to a diameter of 7 mm are pumped away without problems.

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.
