Dülmen micro-tunneling, Germany

The Project:


Dülmen canal construction - micro tunneling, Germany


Executing company:

Fa. Jordan Tiefbau GmbH & Co. KG

Kierdorfer Str. 65

D-50169 Kerpen


The Problem:


The soil loosened at the fron when heading is returned to the pressing pit and must be removed here and disposed.


Our Solution:


The viscous concentrated soil could be sucked off ba a KTZ pump with "suction hat" (reversed inlet strainer).

The specific advantage was the operation of the pump which could be used also during pressing. Transporting off was simple as it was possible to pump the drilling material directly into the containers provided.

No tank truck was necessary.

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.
