Rubberized Impellers for Sludge Pumps

Tsurumi, one of the major manufacturers of dewatering and sewage pumps, is replacing one of its best-selling series. The reason for this is a significant increase in performance: The heavy-duty dewatering pumps for sand and slurry, previously known as KRS2, have been extensively upgraded and are now known as KRD.

By combining optimal hydraulics and wear-resistant materials of construction in a pump replacement, Sulzer helped a leading phosphate fertilizer producer to increase productivity. Sulzer’s AHLSTAR WPP endsuction single-stage pump has proven to be the right choice. It meets the performance requirements while using less energy and drastically cutting maintenance frequency.

Cornish Metals Inc. is using eight Bredel 40 hose pumps and three Qdos chemical metering and dosing pumps from Watson-Marlow Fluid Technology Solutions (WMFTS) in its newly opened water treatment plant (WTP) at South Crofty tin mine in Cornwall, England.

A Peruvian mining company reuses process water as part of their iron ore processing. Until November 2019, however, this was made difficult by the fact that the medium, which is collected in a tank on site, has a very high solids content of 60 to 70 per cent. After an attempt to drain the water and remove the sediment in the tank with shovels had failed after four days, the owner decided to purchase a submersible pump with an agitator.

Ma’aden Wa’ad Al Shamal Phosphate Company (MWSPC) is a leading player in phosphate fertilizers. Its complex in Umm Wu’al, Kingdom of Saudi Arabia, includes a world- class phosphoric acid plant. Sulzer was selected to supply the gypsum evacuation booster pumps needed to evacuate gypsum cake resulting from the filtration of phosphoric acid slurry.

Increasing limitations on sludge disposal is pushing industrial companies to rethink onsite wastewater treatment processes, says Simon Kimber, director, WPL & Atana. This means efficient dewatering to reduce sludge volumes has never been more vital.
