Weir Minerals Africa : Pumping innovation underpins GEHO success

The technical advancement of Weir Minerals’ GEHO® constructive displacement pumps has ensured they play a key function in decreasing mines’ environmental footprint.
The GEHO® pump vary is well-known in various pumping functions together with tailings, backfill, ore transportation and dewatering. Weir Minerals Global Product Manager for GEHO® constructive displacement (PD) pumps, Erik Vlot, highlights the pumps’ capacity to pump highly viscous slurry, permitting mines to conserve water. The energy efficiency of pipeline transportation additionally helps reduce vitality prices and reduces mines’ carbon footprint.
“The basis of GEHO pumps’ success is our ongoing attention to technical innovation and improvement,” says Vlot. “This additionally allowed us to be pioneers in the pumping of very acidic material at high temperatures, similar to nickel slurry at greater than 200°C at a mine in Madagascar.”
With their high capability, GEHO® pumps transport bauxite or iron ore over hundreds of kilometres, providing some of the value efficient and sustainable switch strategies obtainable to the mining trade. These pumps have additionally performed an integral role in the success of a Weir Minerals paste answer at Finland’s largest open pit mine. Yara’s Siilinjärvi mine uses GEHO® pumps to move tailings from the plant, achieving the necessary beach slope on its tailings facility to satisfy its life-of-mine technique.
Backfilling is a crucial methodology for mining to attain security and environmental targets, and GEHO® pumps have been enabling this work. In a North American platinum operation, the gear pumps over a thousand litres a minute of this viscous backfill materials – measuring 70% solids by weight – back into the mine’s worked out areas.
In the context of deep mines, GEHO® pumps provide an efficient and reliable method of dewatering from nice depths, as an alternative of using a quantity of smaller pumps to transfer water to floor. The powerful GEHO® pump vary can do that by pumping from the bottom of a mine to the floor in just one raise – even over kilometres.
“Apart from the cost effectiveness of this resolution, an necessary benefit is that it reduces the chance of 1 pump in a pumping chain failing, and disrupting the complete dewatering function,” he says. “It also reduces the cost and maintenance necessities of having a number of pumping stations at totally different ranges inside the mine.”
The status of GEHO® pumps has additionally been constructed on their reliability, he explains. This has resulted from Weir Minerals’ ongoing research and improvement into its pumps’ put on parts. pressure gauge วัด แรง ดัน น้ำ of is predicated on an in-depth understanding of the entire pumping system during which the pump operates.
“Taking into account how our pumps work together with these techniques, we give attention to key elements of the pumps such as the diaphragm and propelling liquid system,” he says. The propelling liquid offers the barrier between the piston and the diaphragm ensuring that all the shifting parts move in oil and never slurry.
He emphasises the significance of diaphragm dynamics and the necessity to control the quantity of propelling liquid in the chamber. This is done via the PLC control, to make certain that the diaphragm runs in the proper position.
pressure gauge weksler ราคา is good at bending, but if it stretches it could possibly tear,” he says. “Our goal is to increase the alternative intervals between diaphragm replacements, helping mines to scale back both their downtime and their total cost of ownership.”
The monitoring of GEHO® pumps’ operation is conducted through digital technology so that operators can keep abreast – in real time – of the pump’s performance and condition. Weir Minerals’ digital layer for these pumps is being rolled out to clients, informing the upkeep schedules and enhancing pump availability.
Vlot notes that Weir Minerals continues to innovate with the GEHO® pump vary, and is even exploring possibilities for transferring coarse ore to the surface from deep in a mine – as a less expensive choice to conventional hoisting strategies.
“Vital to all our GEHO pump options is the Weir Minerals’ global service community, guaranteeing that wherever our pumps are working there will be an experienced local service crew to assist them,” he concludes.
