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 VF125 - large hose pump used in mining - waterval-smelter.jpg Additionally, reversible hose pumps can be used to clear chokes in the thickener underflew line. In dosing galleries, the variable nature of the corrosive reagents causes diaphragm pumps to clog leading to increased chemical usage and lower plant efficiencies, whereas progressive cavity pumps suffer from burnt stators as they are allowed to run dry. This has lead to peristaltic pumps being specified in floatation cells, primary mineral and tailings retreatment plants and heap leaching installations worldwide.
The rubber hose is capable of pumping slurries containing:
Peristaltic hose pumps have many applications in the mine:
The Verderflex VF125 is the world’s largest high pressure hose pump and can of pump high SG slurries at over 60m3/hour or 260 GPM. The Verderflex VF125 and VF100 are both ideal for the heaviest duty tasks such as ciruclating slurry and thickener underflow.
