Pumps for mining backfilling applications; Solutions for thickened slurry backfilling

Mining Engineering , 2019, Vol. 71, No. 1, pp. 31-31


Pumping backfilling medium used to fill in holes and caverns in mines is challenging. The often viscous, high solids materials are extremely abrasive and can destroy pumping systems in a matter of days. While a number of options are available, using a progressing cavity pump can often be the best solution. High pressure and capacity capabilities, coupled with low wear rates, ensures reliable cost effective operation.
