Nedmag, a leading company in salt mining, implemented two new pumping plants from Waterkracht for more efficient magnesium chloride extraction. This case describes Nedmag's challenges, Waterkracht's solutions and the results of the latest salt extraction site.
Nedmag, based in Veendam, extracts high-quality magnesium chloride from a unique salt layer at a depth of 3,000 metres, a remnant of the Zechstein Sea. With three locations in the Netherlands, Nedmag produces various products, such as Dead Burned Magnesia (DBM), magnesium hydroxide and calcium chloride.
These products are used worldwide for refractory bricks, paper pulp and smoothing. But also within sectors such as the food, cosmetic and medical industries. Thanks to its own R&D department and laboratory, Nedmag guarantees the highest quality for customers in Europe, North America, the Middle East and Asia.
For salt extraction, Nedmag works with special pumping plants that reach depths of up to 3,000 metres. These installations pump water to the surface, dissolve the salt layer and then extract it. The raw material is then processed into finished products at the plant. A slow and precise process, where extreme precision is of great importance.
A new salt extraction site required two new pumping plants: a 24/7 operative plant and a back-up. These had to meet the following conditions:
Nedmag knew exactly what specifications were needed for the installations. In one conversation, all the requirements became clear and the process began at Waterkracht.
The drawings of the new site were the start of the process. This way, we knew exactly where the machines were going to be located and how the infrastructure of the water pipes was put together.
We selected the HDP800 as the pump for installation:
Nedmag's new plant is running at full speed! The entire process -from the pumps to the site and piping- is running 'like clockwork'.
Good service is of great importance for installations that operate day and night and need to be precise. That is why Nedmag's specialists carry out maintenance themselves. Waterkracht trained these people and gradually transferred all maintenance work to them. Is Nedmag unable to do it itself? Then Waterkracht's team is ready with a suitable solution.
