Remediation, wastewater sewer, Cologne
		The Project: Remediation of a wastewater sewer, stormwater treatment SKO 405 Cologne Executing company: F.C. Trapp Tief- und Straßenbau Köln GmbH The Problem: Pumping of the wastewater arising during the 8month construction period including complete construction and laying out of a DN 250 pressure line with a length of 1200 m including overpasses and transverse sections.
Our Solution: Three wastewater pumps of type 100C411 with non-clog impeller with cutter were used. The special impeller comminutes solid matter that arises so that blockages cannot occur. Operational reliability held the highest priority here.
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, 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 conditions of sales (www.tsurumi-europe.com/english/GCS.htm) that we also send to you by mail on request.
