The technical development of Weir Minerals’ GEHO® constructive displacement pumps has ensured they play a key role in reducing mines’ environmental footprint.
The GEHO® pump range is well-known in numerous pumping purposes together with tailings, backfill, ore transportation and dewatering. Weir Minerals Global Product Manager for GEHO® constructive displacement (PD) pumps, Erik Vlot, highlights the pumps’ ability to pump extremely viscous slurry, permitting mines to conserve water. The energy efficiency of pipeline transportation also helps cut vitality costs and reduces mines’ carbon footprint.
“The basis of GEHO pumps’ success is our ongoing attention to technical innovation and enchancment,” says Vlot. “ เกจวัดแรงดัน allowed us to be pioneers within the pumping of very acidic material at excessive temperatures, such as nickel slurry at more than 200°C at a mine in Madagascar.”
With their high capacity, GEHO® pumps transport bauxite or iron ore over hundreds of kilometres, providing one of the cost effective and sustainable transfer strategies out there to the mining trade. These pumps have additionally played 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, achieving the necessary seashore slope on its tailings facility to fulfill its life-of-mine technique.
Backfilling is an important method for mining to achieve security and environmental goals, 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 – again into the mine’s labored out areas.
In the context of deep mines, GEHO® pumps present an efficient and reliable method of dewatering from nice depths, instead of using a number of smaller pumps to switch water to floor. The highly effective GEHO® pump range can do that by pumping from the bottom of a mine to the floor in just one carry – even over kilometres.
“Apart from เกจวัดแรงดัน of this resolution, an necessary advantage is that it reduces the chance of 1 pump in a pumping chain failing, and disrupting the entire dewatering operate,” he says. “It also reduces the price and maintenance requirements of getting multiple pumping stations at different levels throughout the mine.”
The popularity of GEHO® pumps has additionally been built on their reliability, he explains. digital pressure gauge has resulted from Weir Minerals’ ongoing research and growth into its pumps’ wear components. This process is based 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 systems, we concentrate on 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 each one the shifting parts transfer in oil and never slurry.
He emphasises the significance of diaphragm dynamics and the want to management the quantity of propelling liquid in the chamber. This is completed through the PLC control, to ensure that the diaphragm runs in the best place.
“Rubber is good at bending, but when it stretches it could tear,” he says. “Our purpose is to increase the replacement intervals between diaphragm replacements, helping mines to minimize back each their downtime and their total price of ownership.”
The monitoring of GEHO® pumps’ operation is carried out through digital know-how so that operators can stay abreast – in real time – of the pump’s efficiency 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 potentialities for transferring coarse ore to the floor from deep in a mine – as a more price effective option to traditional hoisting strategies.
“Vital to all our GEHO pump solutions is the Weir Minerals’ international service network, making certain that wherever our pumps are working there will be an experienced native service crew to support them,” he concludes.
