New test bench in operation

A milestone for quality and the future

Kiel | Germany, July 2025 – After almost two years of intensive planning and implementation, the time has finally come: EDUR has put its new test facility into operation. Five new test bench stations have been created since construction started in February 2024, completely replacing the two previous test benches. The company has invested two million euros in the new testing technology. With this investment, the company is positioning itself for the future and taking centrifugal pump testing to a new level.

EDUR’s policy has always been that every single pump is checked for the agreed performance before delivery. Only pumps that meet the desired requirements are dispatched to the customer. However, the two test benches previously used were increasingly becoming a bottleneck in the process chain. Now it’s a thing of the past.

Thanks to two separate tanks, each with a capacity of 18,000 liters – one for stainless steel pumps and one for other material groups – up to five pumps can now be tested or prepared for acceptance in parallel. Both tanks are filled with deionized water, and the tank for stainless steel pumps also contains disinfectant additives. This is how EDUR aims to meet the high requirements of the high-purity sector, for example.

Technically, EDUR is setting new standards with its test bench: flow rates up to 600 m³/h, pressures up to PN40, and voltages up to 500 V. This means that the company can now test all centrifugal pumps in its own factory in accordance with global standards. NPSH tests according to DIN EN ISO 9906:2013-3 for all series and sizes are now also standard – to the benefit of customers worldwide.

In addition, the new system also brings significant improvements to the workflow: Instead of screwing the flanges together as before, the pumps can now be clamped hydraulically quickly and easily, which reduces setup times. The flow of the medium in the test procedure can also be controlled much more quickly and precisely. The pumps can now be preserved directly on the test bench, meaning that they can be sent straight to the paint shop afterwards. Previously, an additional step was required for preservation. Test reports are now transferred directly to the IT documentation system using the appropriate interfaces. However, investments have been made not only in process optimization, but also in employee safety, for example through protective walls, additional electrical safety devices, and significant reductions in noise emissions. The new test bench was implemented in collaboration with Fladt Engineering, based in Kehl in southern Germany.

The comprehensive construction work was carried out during ongoing operations. The more complex tasks included relocating the existing test bench and rotating the crane runway with a weight of 5 tons to create space for the new test facility. Due to their size, the precise installation of the tanks and also the sound insulation system were among the major milestones in the course of the project. But the effort has paid off. With the new test facility, EDUR is sending a clear signal to the outside world and is highly motivated for the upcoming pump projects.
