The technical development of Weir Minerals’ GEHO® constructive displacement pumps has ensured they play a key role in decreasing mines’ environmental footprint.
The GEHO® pump vary is well-known in varied pumping functions including tailings, backfill, ore transportation and dewatering. Weir Minerals Global Product Manager for GEHO® optimistic displacement (PD) pumps, Erik Vlot, highlights the pumps’ ability to pump extremely viscous slurry, allowing mines to preserve water. The energy effectivity of pipeline transportation also helps reduce vitality costs and reduces mines’ carbon footprint.
“The foundation of GEHO pumps’ success is our ongoing attention to technical innovation and improvement,” says Vlot. “This also allowed us to be pioneers within the pumping of very acidic material at high temperatures, similar to nickel slurry at more than 200°C at a mine in Madagascar.”
With their high capacity, GEHO® pumps transport bauxite or iron ore over tons of of kilometres, offering one of the most value effective and sustainable transfer methods available to the mining industry. These pumps have additionally played an integral function in the success of a Weir Minerals paste solution at Finland’s largest open pit mine. Yara’s Siilinjärvi mine makes use of GEHO® pumps to maneuver tailings from the plant, achieving the required seashore slope on its tailings facility to fulfill its life-of-mine technique.
เกจวัดแรงดันน้ำราคา is a crucial methodology for mining to attain 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 material – 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 means of dewatering from great depths, as an alternative of using a quantity of smaller pumps to transfer water to floor. The highly effective GEHO® pump range can do this by pumping from the bottom of a mine to the floor in only one carry – even over kilometres.
“Apart from the cost effectiveness of this resolution, an important advantage is that it reduces the risk of 1 pump in a pumping chain failing, and disrupting the complete dewatering operate,” he says. “It additionally reduces the price and upkeep necessities of getting a number of pumping stations at completely different levels within the mine.”
The status of GEHO® pumps has also been constructed on their reliability, he explains. This has resulted from Weir Minerals’ ongoing research and growth into its pumps’ put on components. This process is predicated on an in-depth understanding of the whole pumping system during which the pump operates.
“Taking under consideration how our pumps interact with these methods, we give attention to key aspects of the pumps such because the diaphragm and propelling liquid system,” he says. The propelling liquid offers the barrier between the piston and the diaphragm ensuring that every one the transferring elements transfer in oil and never slurry.
He emphasises the significance of diaphragm dynamics and the necessity to management the amount of propelling liquid within the chamber. This is done by way of the PLC management, to ensure that the diaphragm runs in the proper position.
“Rubber is sweet at bending, but when it stretches it can tear,” he says. “Our purpose is to extend the substitute intervals between diaphragm replacements, serving to mines to reduce each their downtime and their total price of ownership.”
The monitoring of GEHO® pumps’ operation is conducted via digital expertise in order that operators can stay 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 range, and is even exploring possibilities for transferring coarse ore to the surface from deep in a mine – as a more cost effective choice to traditional hoisting strategies.
“Vital to all our GEHO pump options is the Weir Minerals’ global service community, making certain that wherever our pumps are working there shall be an experienced native service crew to assist them,” he concludes.
