New Indian Steel Plant Will Receive 11 De-Scaling Pumps From RMI

Destined for the thin slab production line, the pumps will form the heart of two de-scaling pump stations, each of which will handle in excess of 205 tonnes per hour.

RMI has designed and manufactured a carefully engineered solution that will be integrated into the thin slab rolling part of the project which is being installed by Danieli. The project in Nagarnar will incorporate two pump stations, producing 1,870 l/min and 2,380 l/min respectively at 400 bar. Each station is designed to deliver optimum pressure and flow according to the steel type in production, thereby optimising production costs and efficiency.

Mike Sherman, Marketing Manager for RMI, comments: "This de-scaling solution has been characterised by a combination of variable speed and fixed speed pumps with high flow rates and the application of an optimised nozzle pattern. The benefits of this de-scaling package are reduced investment costs and lower maintenance costs as well as substantial energy savings due to flexible operation according to the process requirements."

The S500 Quinmax pump features a five piston crankshaft which allows it to pump higher flow rates (340 – 1080 l/min) at greater pressure (190 – 1000 bar) with reduced loads on the shaft and bearings for greater periods before service intervals. The range is driven by 300 – 400kW motors and feature ram diameters spanning from 50mm to 80mm.
