pressure gauge ลม of Weir Minerals’ GEHO® optimistic displacement pumps has ensured they play a key role in lowering mines’ environmental footprint.
The GEHO® pump vary is well-known in numerous pumping applications together with tailings, backfill, ore transportation and dewatering. Weir Minerals Global Product Manager for GEHO® optimistic displacement (PD) pumps, Erik Vlot, highlights the pumps’ capacity to pump highly viscous slurry, allowing mines to conserve water. The power efficiency of pipeline transportation also helps cut vitality costs and reduces mines’ carbon footprint.
“The foundation of GEHO pumps’ success is our ongoing consideration to technical innovation and improvement,” says Vlot. “This additionally allowed us to be pioneers in the pumping of very acidic materials at excessive temperatures, corresponding to nickel slurry at more 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 cost effective and sustainable switch strategies obtainable to the mining trade. These pumps have additionally played an integral function within the success of a Weir Minerals paste resolution 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 meet its life-of-mine strategy.
Backfilling is a crucial technique for mining to achieve security and environmental objectives, 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 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 dependable means of dewatering from nice depths, as an alternative of utilizing a number of smaller pumps to switch water to floor. The powerful GEHO® pump vary can do this by pumping from the bottom of a mine to the floor in only one carry – even over kilometres.
“Apart from the fee effectiveness of this solution, an essential advantage 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 fee and maintenance requirements of having a quantity of pumping stations at totally different levels within the mine.”
The popularity of GEHO® pumps has additionally been built on their reliability, he explains. This has resulted from Weir Minerals’ ongoing research and improvement into its pumps’ wear elements. This process relies on an in-depth understanding of the entire pumping system by which the pump operates.
“Taking into account how our pumps work together with these methods, we focus on key aspects 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 making certain that every one the transferring components move in oil and not slurry.
He emphasises the significance of diaphragm dynamics and the necessity to control the quantity of propelling liquid within the chamber. This is done via the PLC management, to guarantee that the diaphragm runs in the right place.
“Rubber is good at bending, but if it stretches it could tear,” he says. “Our goal is to extend the substitute intervals between diaphragm replacements, serving to mines to scale back each their downtime and their whole price of possession.”
The monitoring of GEHO® pumps’ operation is carried out through digital technology so that operators can stay abreast – in actual time – of the pump’s performance and situation. 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 less expensive choice to traditional hoisting methods.
“Vital to all our GEHO pump solutions is the Weir Minerals’ world service community, making certain that wherever our pumps are working there shall be an experienced native service crew to support them,” he concludes.
