EJECTOR TECHNOLOGY: CUSTOMISED SOLUTIONS FOR SPECIAL SHIPS
With more than 140 years’ experience in the ejector technology, Körting Hannover AG can offer highly efficient and proven solutions for the shipbuilding industry. The current project for a shipyard shows just how customsed these solutions can be.
The customer appointed Körting Hannover AG to produce bilqe ejectors for a suction capacity of more than 650 m3/h.
A new generation of the existing product range was required and bilge ejectors with a nominal size of DN350 had to be developed and manufactured. “What made the project so special was that we managed to comply with and implement the customers’ special demands in a short space of time.
Something other competitors couldn’t manage to do”, explains Markus Kampers, project engineer at Körting Hannover AG.
Testing capacities were quickly expanded to check the performance of the jet ejectors. Because it was vital to supply the quantity that streams through the jet ejector and measure it very precisely. On site, Körting Hannover AG had a total volume of 250 m3 of water which is circulated about three times per hour. As a result, a performance record for the Germanischer Lloyd (GL) classification society was provided directly in the main plant in Hanover, Germany. The cooperation of all internal departments led to the success of the project.
Internationally Körting is the only company whose ejectors are fully GL-certified.
“Foresightedly the design of the new ejectors was chosen to get the approval from any classification society”, explains Kampers when outlining one of the many benefits Körting offers.
As the leading and at the Same time oldest supplier of jet ejector technology, Körting delivers customised solutions to its customers. All jet ejectors are custom-made to performance specifications. “Cavitation-free operation, minimal energy consumption and maximum suction power are the results of our customised design”, reports Kampers.
The jet ejectors in nominal widths of DN350 are made of high-quality, fully seawater-resistant cast bronze. “This allows us to achieve low weight, but extreme strength. What’s more the jet ejectors are verv hard-wearing”. Thev have no electrical or mechanicaL drives, dynamic seals or moving parts. Therefore, jet ejectors stand apart because they have perfect dryrunning capabilities, don’t get dirty easily and are consequently virtually maintenance-free. “The current project shows that Körting is fully capable of reacting to any conceivable enquiry from a customer thanks to its experience, flexibility and highly professional approach’, says Kampers.
