Geothermal drilling, Marl, Germany

The project:

Geowell Erdwärme in Marl, with an office in Bichl bei München, plans and implements geothermal installations throughout Germany and abroad. Holes 25 metres to 300 metres deep are drilled in every possible geological formation and rock in Germany. Geowell Erdwärme relies on powerful, reliable technology for its drilling operations, since failures can be problematic and expensive. Geowell Erdwärme relies on Tsurumi pumps.


Executing company:

Geowell Erdwärme GmbH & Co. KG, Marl

Biergans Pumpen-Vertrieb GmbH, Duisburg


Tsurumi consultants:

Mr. Stefan Himmelsbach (Product Manager Construction Pumps)


The problem:

Pumping drilling water with a high sediment load


The solution:

The use of Tsurumi series HS and KTV pumps. These series are robust and wear-resistant, while remaining lightweight and transportable.

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.
