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 vary is well-known in various pumping purposes together with tailings, backfill, ore transportation and dewatering. Weir Minerals Global Product Manager for GEHO® positive displacement (PD) pumps, Erik Vlot, highlights the pumps’ capacity to pump extremely viscous slurry, allowing mines to conserve water. The energy efficiency of pipeline transportation also helps minimize vitality prices and reduces mines’ carbon footprint.
“The basis of GEHO pumps’ success is our ongoing attention to technical innovation and enchancment,” says Vlot. “This also allowed us to be pioneers within the pumping of very acidic materials at high temperatures, similar to nickel slurry at greater than 200°C at a mine in Madagascar.”
With their excessive capacity, GEHO® pumps transport bauxite or iron ore over lots of of kilometres, offering one of the most value effective and sustainable transfer methods out there to the mining trade. These pumps have additionally performed an integral role in the success of a Weir Minerals paste solution at Finland’s largest open pit mine. Yara’s Siilinjärvi mine uses GEHO® pumps to maneuver tailings from the plant, reaching the required beach slope on its tailings facility to fulfill its life-of-mine technique.
Backfilling is a vital methodology for mining to realize security and environmental targets, and GEHO® pumps have been enabling this work. In a North American platinum operation, the tools pumps over a thousand litres a minute of this viscous backfill materials – measuring 70% solids by weight – back into the mine’s labored out areas.
In the context of deep mines, GEHO® pumps provide an environment friendly and dependable way of dewatering from nice depths, as an alternative of using multiple smaller pumps to transfer water to floor. The powerful GEHO® pump vary can do that by pumping from the underside of a mine to the floor in only one lift – even over kilometres.
“Apart from the cost effectiveness of this solution, an essential benefit is that it reduces the chance of 1 pump in a pumping chain failing, and disrupting the complete dewatering operate,” he says. “It also reduces the cost and maintenance requirements of getting a number of pumping stations at completely different levels throughout the mine.”
The popularity of GEHO® pumps has additionally been built on their reliability, he explains. This has resulted from Weir Minerals’ ongoing analysis and improvement into its pumps’ put on elements. This course of is predicated on an in-depth understanding of the whole pumping system in which the pump operates.
“Taking under consideration how our pumps interact 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 supplies the barrier between the piston and the diaphragm ensuring that each one the moving components move in oil and never slurry.
He emphasises the importance of diaphragm dynamics and the need to control the quantity of propelling liquid within the chamber. This is completed through the PLC management, to ensure that the diaphragm runs in the proper place.
pressure gauge nuova fima ราคา is good at bending, but if it stretches it could tear,” he says. “Our goal is to increase the substitute intervals between diaphragm replacements, serving to mines to scale back each their downtime and their complete value of ownership.”
The monitoring of GEHO® pumps’ operation is carried out by way of digital know-how so that operators can keep abreast – in actual time – of the pump’s efficiency and situation. Weir Minerals’ digital layer for these pumps is being rolled out to prospects, informing the maintenance 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 floor from deep in a mine – as a less expensive choice to conventional hoisting methods.
“Vital to all our GEHO pump options is the Weir Minerals’ global service network, making certain that wherever our pumps are working there might be an experienced local service crew to help them,” he concludes.
