Weir Minerals Africa : Pumping innovation underpins GEHO success

The technical advancement of Weir Minerals’ GEHO® optimistic displacement pumps has ensured they play a key function in lowering mines’ environmental footprint.
The GEHO® pump range is well known in numerous pumping functions together with tailings, backfill, ore transportation and dewatering. Weir Minerals Global Product Manager for GEHO® optimistic displacement (PD) pumps, Erik Vlot, highlights the pumps’ capability to pump highly viscous slurry, allowing mines to conserve water. The power effectivity of pipeline transportation also helps cut energy costs and reduces mines’ carbon footprint.
“The foundation of GEHO pumps’ success is our ongoing attention to technical innovation and improvement,” says Vlot. “This additionally allowed us to be pioneers within the pumping of very acidic materials at high temperatures, corresponding to nickel slurry at greater than 200°C at a mine in Madagascar.”
With pressure gauge ออก หลัง , GEHO® pumps transport bauxite or iron ore over lots of of kilometres, providing one of the price effective and sustainable transfer strategies available to the mining trade. These pumps have also performed an integral function in the success of a Weir Minerals paste answer at Finland’s largest open pit mine. Yara’s Siilinjärvi mine uses GEHO® pumps to maneuver tailings from the plant, achieving the mandatory beach slope on its tailings facility to satisfy its life-of-mine strategy.
Backfilling is an important technique for mining to achieve safety and environmental targets, and GEHO® pumps have been enabling this work. In a North American platinum operation, the equipment pumps over a thousand litres a minute of this viscous backfill materials – measuring 70% solids by weight – again into the mine’s labored out areas.
In the context of deep mines, GEHO® pumps present an environment friendly and reliable way of dewatering from nice depths, instead of using multiple smaller pumps to switch water to surface. The powerful GEHO® pump vary can do that by pumping from the bottom of a mine to the floor in just one carry – even over kilometres.
“Apart from the price effectiveness of this resolution, an important benefit is that it reduces the risk of one pump in a pumping chain failing, and disrupting the whole dewatering function,” he says. “It also reduces the cost and upkeep necessities of getting multiple pumping stations at different ranges throughout the mine.”
The status of GEHO® pumps has additionally been constructed on their reliability, he explains. This has resulted from Weir Minerals’ ongoing analysis and growth into its pumps’ put on components. This process relies on an in-depth understanding of the whole pumping system by which the pump operates.
“Taking into consideration how our pumps work together with these systems, we concentrate on key features of the pumps such as the diaphragm and propelling liquid system,” he says. The propelling liquid supplies the barrier between the piston and the diaphragm making certain that every one the shifting components transfer in oil and not slurry.
He emphasises the significance of diaphragm dynamics and the necessity to control the volume of propelling liquid in the chamber. This is completed through the PLC management, to ensure that the diaphragm runs in the right position.
“Rubber is nice at bending, but when it stretches it could possibly tear,” he says. “ compound gauge ราคา is to increase the substitute intervals between diaphragm replacements, helping mines to reduce back both their downtime and their complete cost of possession.”
The monitoring of GEHO® pumps’ operation is carried out by way of digital technology so that operators can keep abreast – in real time – of the pump’s performance and situation. Weir Minerals’ digital layer for these pumps is being rolled out to prospects, informing the upkeep schedules and enhancing pump availability.
Vlot notes that Weir Minerals continues to innovate with the GEHO® pump range, and is even exploring prospects for transferring coarse ore to the floor from deep in a mine – as a more economical choice to conventional hoisting methods.
“Vital to all our GEHO pump solutions is the Weir Minerals’ world service network, ensuring that wherever our pumps are working there might be an skilled local service crew to help them,” he concludes.
