Weir Minerals’ high wall pump for flooded mines
Global mine dewatering specialist Weir Minerals Multiflo says its latest pump, the Multiflo High Wall, was developed in response to demand from mining customers affected by recent floods, such as the Queensland disasters of 2011 and 2012.
A typical site for a high wall pump application.
According to Weir, the Multiflo HW pump offers a range of new and unique patent-pending features, including an environmentally friendly dual pipe system that separates hydraulic oil hoses from the dedicated discharge pipe, to reduce the risk of hydraulic oils contaminating discharge water.
The submersible pump head assembly includes hydraulic-driven wheels to aid high wall ascent and descent, and a heavy duty hydraulic-driven submersible pump designed to handle high concentrations of silt and solids.
WMM marketing manager, Carlos Vernet, said development of the Multiflo HW was prompted by customer discussions that revealed the need for a superior high wall pump for reliable mine dewatering application.
“According to the Queensland Resource Council, the state’s coal exports fell 40mtpa short of projections because of the 2011 floods. This meant a significant financial loss for the many mines directly impacted by the natural disaster, as well as to the economies of Queensland and Australia.”
Multiflo HW pump also features a modular design for ease of transport and assembly once on site; uses joystick control of the hydraulics for easy operation; has an operator camera for in-pit visibility; and has been designed to ensure maximum flow rates of up to 200 litres per second at 90m head.
Weir begins production of the Multiflo HW in July 2012.
