Challenging environment
By Steve Skinner09 September 2008
A total of 60 Tsurumi pumps were used over a period of four years on Deutsche Bahn’s (German National Railway) Katzenberg tunnel project.
This involved the construction of a 9 km-long rail tunnel between Karlsruhe in Germany and Basel in Switzerland. The project was run as a joint venture comprising Wayss & Freytag, Züblin, Marti and Jäger.
The Japanese manufacturer supplied pumps from its KTZ, KTV and KRS ranges – multi-purpose and heavy sludge pumps, which according to Tsurumi are ideal for use in tough operating environments.
A spokesman for the company said, “One clear difference is Tsurumi’s oil lifter, which uses centrifugal force to ensure constant lubrication of the pump shaft. Proven effective over a number of years, this patented system is now installed in every Tsurumi pump. Competitor manufacturers have only recently begun to offer continual lubrication as an option, which means they are thus far unproven for long-term operation.”
