New pump for deep mining environments
A new self-priming centrifugal single-stage pump range, now available from Integrated Pump Rental (IPR), offers a maximum head of 235 m and a maximum flow of 2 000 m³ and is said to provide efficient pumping needs at extreme mining depths.
Deep opencast mines are becoming more common-place, as near-surface deposits deplete and these operations often experience significant water ingress which can result in flooding, equipment damage and safety hazards.
IPR sales manager Steve du Toit explains that, traditionally, mines have resorted to multi-stage centrifugal dewatering systems to pump water at extreme depths but that the complexity of these systems rises with increasing 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, says Du Toit.
With their high lift capability, the PAC SH pumps are engineered to move water directly from deeper levels of the pit without requiring multiple stages. This translates into easier installations, less equipment requiring maintenance and more efficient dewatering.
“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.
IPR notes that the new pump complements its existing portfolio that includes the VAR, PAS and PAC ranges, enabling the company to now offer a full suite of dewatering solutions for each stage of pit development, from breaking ground to deep levels.
