Verderflex peristaltic pumps are the first choice for mines around the world, offering unrivalled performance in a tough and uncompromising environment. Abrasive mining slurries have sub-micron solid contents in excess of 80% with slurry SGs in excess of 2.0. Only hose pumps can pump such dense fluids whilst maintaining high levels of plant availability unlike centrifugal pumps which suffer from continuous downtime and are unable to pump such high SG slurries, lower plant performance Additionally, reversible hose pumps can be used to clear chokes in the thickener underflow line.

Copper tailings - slurry is very abrasive. Centrifugal pumps with soft packing shaft seals had to be water-flushed to limit wear on the shaft sleeve. Fine until winter froze the water. Solution: a Albin Pump ALHX80, with no seals to wear out. Tailings could be continuously pumped at higher concentrations!, doubling plant efficiency. Downtime: a few minutes every 2,000 hours to change the tube.
