Metso Outotec recently confirmed it delivered an order of 22 mill discharge pumps for customers Engineering Dobersek and Severniy Mining and Processing (SevGOK) to the latter’s process waste thickening plant in Ukraine.
The new group of high-capacity pumps include 10 large high-capacity MDM700s which together are capable of handling a total volume of 117,500 m3 of waste sludge per hour. Each will be tasked with pumping the iron ore concentrate plant’s waste sludge into settling ponds from the thickeners.
The supplier noted that its mill discharge pumps were designed for mill circuit applications such as SAG/ball mill discharge pumps and hydrocyclone feed, but that it focused on placing components that have to withstand exceptional wear from coarse heavy solids and flow turbulence. Metso Outotec’s pumps line can cover flows of up to 12,000 m3/h, with the inlet sizes ranging from 250 mm to 800 mm with metal or rubber linings.
“SevGOK’s complex is the second of its kind in Ukraine, and Engineering Dobersek in Germany has designed it. With this investment, SevGOK aims to decrease environmental impacts and costs by lowering energy consumption and water usage. They chose Metso Outotec pumps because of their reliability and efficiency, and the good support Metso Outotec has provided in their previous projects,” said Axel Stappen, managing director for Engineering Dobersek.
Michael Nienhaus, Metso Outotec head of sales of slurry pumps for Germany, added: “To give an idea of the size of an MDM700 pump, it can weigh as much as 31 tons and be 2.8 meters in diameter, and have an impressive pumping volume of up to 9,650 m3/h. The MDM pumps operate in very demanding conditions, and we’ve designed them to operate reliably and to withstand exceptional wear.”
No timeline for installation was released.
