Our HPC coating has demonstrated itself as the best of its kind market-wide
Wear, corrosion, and deposits are effectively prevented by a smooth surface and improved flow properties, thereby enhancing lifespan and efficiency.

The Queckborn waterworks has a long tradition of treating water from the surrounding area. In addition to meeting the water requirements of its own town, it supplies around 75% of the water requirements of Giessen and pumps several cubic meters of water to the surrounding towns every day. This makes it the heart of the water supply in the surrounding area. The Queckborn waterworks is operated by Stadtwerke Gießen AG.
Stadtwerke Gießen AG is very interested in energy-optimized operation of its plants. Depending on its size, the annual energy requirement of a waterworks is in the six-digit kilowatt range. In order to save energy costs, it is worth investing in high-quality, state-of-the-art pumps at an early stage.
In addition, high process reliability is required for the plant in Queckborn. In the event of a malfunction, large parts of Gießen are without water.
In order to meet the requirements of an energy-reduced, process-safe plant, Herborner Pumpentechnik is supplying seven 100% coated herborner.Fneo pumps in a special design suitable for drinking water. The coating serves to prevent corrosion as best as possible and, together with the sophisticated hydraulics, ensures very high efficiency.
The pumps are significantly quieter than comparable pumps on the market and have also been partially equipped with water cooling. This makes the plant tours offered by the municipal utilities much more pleasant for the guests. The maintenance carriage used here is an absolute novelty. Even the 82 kW pumps can be serviced by a single person. A seal replacement, for example, can be carried out in less than 30 minutes.
The necessary modification of the system and installation of the pumps was partly carried out at night, because the water demand in the area is significantly lower here. In addition, not all pumps were replaced at the same time, but one after the other, so that the waterworks could supply a certain amount of water at any time. They were installed and commissioned by colleagues from our Herborn pump site in Landsberg/Halle in cooperation with the municipal utilities in Giessen and Weiteren.
"We have also had very good experience with Herborn pumps before. I am therefore convinced that modernizing the pumps at the Queckborn waterworks in this way was an important step and that we will save a lot of energy over time." Christian Francke, the project manager of the project, is pleased.
The project enables energy savings of over 10% with full corrosion protection and additional process reliability that could not be guaranteed in this form before. The measure was funded by the German Federal Ministry for the Environment through the project management organization Jülich with the National Climate Protection Initiative - Municipal Guidelines funding program.
