Maximising dewatering efficiency at extreme depths Offering a maximum head of 235 m and a maximum flow of 2 000 m³/h, the new Atlas Copco PAC SH self-priming centrifugal single-stage pump range, now available from IPR, provides a suitable dewatering solution for deep mining environments without the need for complex, costly multistage pumping systems.
T he latest from IPR is the Atlas Copco PAC SH self-priming centrifugal single- stage pump range. With a maximum head of 235 m and a maximum flow of 2 000 m³/h, the range – the largest in IPR’s expansive dewatering portfolio – is the answer to efficient pumping needs at extreme mining depths. Amid growing global demand for minerals, deep opencast mines have become an industry reality as near-surface deposits deplete rapidly. These operations often contend with significant water ingress, which, if not properly managed, can result in flooding, equipment damage and safety hazards. Steve du Toit, Sales Manager at IPR, says that, traditionally, mines have resorted to multi-stage centrifugal dewatering systems to pump water from extreme depths. However, the complexity of these systems increases with mining depth. The addition of piping and pumping stations in multi-stage set-ups not only requires more equipment but also increases maintenance needs. With their high lift capability, Du Toit says, PAC SH pumps can move water directly from deeper levels of the pit without requiring mul- tiple stages. This translates into easier instal- lations, less equipment to maintain, and more efficient dewatering, allowing deepening mines to cut costs and increase efficiency. “The PAC SH self-priming centrifugal single- stage pump range stands out due to its ability to deliver greater lift and efficiency than con -
ventional multi-stage centrifugal dewatering systems often used at extreme depths. The advanced design and capabilities mean that fewer pumps are needed, set-up is simpler, and performance is more consistent in deep pit dewatering applications,” Du Toit says. The PAC SH complements an existing broad portfolio that already includes the VAR, PAS and PAC ranges, allowing IPR to offer mines a full suite of dewatering solutions for each stage
of pit development, from breaking ground to deep levels. “The extended PAC range means mines can now match the right pump to each stage of pit development – from medium depth to very deep pits. This flexibility ensures efficiency at every stage and provides operational teams with the confidence that the right solution is always available,” Du Toit concludes. https://www.pumprental.co.za/
The PAC SH pump streamlines deep pit dewatering by reducing the number of pumps required and simplifying the overall setup.
