The project:

An artificially created lake serving as a reservoir for fire protection, a biotope, and watering place for animals.


Company carrying out the works:

Elektromaschinenbau Schmid, Eglfing


Tsurumi supervisor:

Mr. Christian Kulik (Field Sales Team Bavaria)


The problem:

In the summer months, the standing water tends to silt up and towards "environmental collapse". A natural inflow or outflow does not exist.


The solution:

Introduction of oxygen by means of submersible aerators. Three submersible aerators were deployed, each with a motor output of 0.75 kW, which blows ambient air into the water and, thereby, increases the oxygen level. An even admixture in the water is ensured through the arrangement of the submersible aerators in the stretch of water. In the summer months, the aerators are in continuous operation, while they are operated on an as-needed basis during the remaining months. Three smaller aerators were consciously selected since a single, large aerator would not be able to guarantee an even admixture.

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.
