National Pump and Energy supplied a complete dewatering solution for wet season dewatering at a Northern Territory mine site.
The custom package delivered duty requirements of 2000L/sec at 17m TDH. To achieve these impressive flows, NPE selected two Macquarrie 26HBC-30, 220kW electric driven pontoon pumps.
They pumped to the same pumps on skids onshore.
The two separate trains achieved 1000L/sec, performing flawlessly for the four month rental project.
NT branch operations manager David Fanning said the operations team proudly supplied the large dewatering package on time and provided ongoing support for the duration of the project.
“We were able to tailor a sophisticated pumping solution for the client’s needs and take the hassle out of wet season dewatering,” Mr Fanning said.

What is TDH?
Total Dynamic Head, the work done by the pump per unit weight, per unit volume of fluid.
TDH = Pumping Level + Vertical Rise + Friction Loss.
