Engineering Dobersek in Germany and Severniy Mining and Processing (SevGOK) in Ukraine have selected Metso Outotec’s mill discharge pumps for Severniy’s greenfield process waste thickening plant, the OEM says.

Metso Outotec’s pumps will be used to pump the iron ore concentrate plant’s waste sludge into the settling ponds from the thickeners. The 22 pumps to be delivered by Metso Outotec include 10 large high-capacity MDM700 pumps. Together, the pumps are capable of handling a total volume of 117,500 cu.m/h of waste sludge.

“SevGOK’s complex is the second of its kind in Ukraine, and Engineering Dobersek in Germany has designed it,” Axel Stappen, Managing Director, Engineering Dobersek GmbH, says. “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.”

Michael Nienhaus, Head of Sales, Slurry Pumps, Germany, Metso Outotec, says: “We are delighted to have been selected to supply our MD series pumps to SevGOK’s project. To give an idea of the size of an MDM700 pump, it can weigh as much as 31 t and be 2.8 m in diameter, and have an impressive pumping volume of up to 9,650 cu.m/h. The MDM pumps operate in very demanding conditions, and we’ve designed them to operate reliably and to withstand exceptional wear.”

Metso Outotec mill discharge pumps have been designed for mill circuit applications, such as SAG/ball mill discharge pumps and hydrocyclone feed. Special emphasis has been placed on components that have to withstand exceptional wear from coarse heavy solids and flow turbulence, the company says.
