Bad Wurzach treatment plant, Germany

The Project:

Eintürnen pumping station of the Bad Wurzach treatment plant


Hurter, Leutkirch

Tsurumi support:

Ernst Mutzel (Field Sales Baden-Württemberg)

The Problem:

The pumping station has always had problems with clogging, and the treatment-plant workers sometimes have to clean the pumps several times a week. Pumps from different manufacturers were tested, but with no improvement in the situation.

The Solution:

Use of a type 100C43.7 cutter pump with a tungsten-carbide blade built into the impeller. This pump shifts large quantities of wastewater and shreds fibrous materials using the built-in cutting mechanism. After ten months, there was not a single case of clogging.


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.
