Essen-Kettwig sewage treatment plant, Germany

The Project:

Activated sludge tank for Essen-Kettwig treatment plant, Germany

Executing company: Hochtief Civil

Equipment provided by Streif Baulogistik

The Problem:

The surface water collected at the concrete floors must be pumped off completely over a wide area.

Our Solution:

A type LSC-4 residue water pump allows to suck off the surface water up to 2mm. The check valve installed below the impeller enables continuous self-priming pumping on snore mode.


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.
