The project:

Rainwater disposal in a ballast works

Executing companies:

Schotterwerk Inh. J. Mayer

Eberle-Hald GmbH&Co.KG, Stuttgart

The problem:

Disposal of rainwater with sand and dirt content, height differential of 30 metres. The 22 kW pump used in the past was to be replaced on account of the high repair costs.

Our solution:

Deployment of a KTZ411 running at 11 kW in its cast iron version. Due to its resistance to the effects of sand, this type of pump is ideal for the use in question. In addition, the motor rating used can be decreased by half. In the adjoining concrete works, a KTZ35.5 at 5.5 kW is also in use in the concrete recycling plant.

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.
