Gravel plant Dillingen, Germany

The project:

The mud streams that occur during gravel washing are bound by means of a flocculent substance and are then pumped into filtration chamber presses with a lime additive.

Company carrying out the works:

Kieswerk Rupp GmbH & Co. KG, Dillingen

Tsurumi supervisor:

Mr. Christian Oremus (Field Sales Team Hessia/Rheinland-Pfalz/Saarland)

The problem:

Due to the high solids content, the medium that has to be pumped is extremely abrasive and causes extensive wear-and-tear.

The solution:

Since 2009, our wear-resistant pump GPN-100 has been used. The relevant wear-and-tear parts, such as the impeller and the wear plate, are exchanged only once each year.

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.
