Latest from IPR (Integrated Pump Rental) is the Atlas Copco PAC SH self-priming centrifugal single-stage pump range. With a maximum head of 235 metres and a maximum flow of 2 000 m³, the range – the largest in IPR’s expansive dewatering portfolio – is the pertinent 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 at a rapid pace. 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 traditionally mines have resorted to multi-stage centrifugal dewatering systems to pump water at extreme depths. However, these systems’ complexity rises with mining depth. The addition of piping and pumping stations in multi-stage set-ups not only calls for more equipment but also increases the need for maintenance.

With their high lift capability, Du Toit says, the PAC SH pumps can move water directly from deeper levels of the pit without requiring multiple stages. This translates into easier installations, less equipment to look after and more efficient dewatering, allowing deepening mines to cut costs and increase efficiencies.

“The PAC SH self-priming centrifugal single-stage pump range stands out due to its ability to deliver greater lift and efficiency than conventional 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.
