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 reducing mines’ environmental footprint.
The GEHO® pump vary is well-known in varied pumping applications including 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 preserve water. The vitality efficiency of pipeline transportation additionally helps minimize energy costs and reduces mines’ carbon footprint.
เครื่องมือใช้วัดความดัน 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 excessive temperatures, such as nickel slurry at greater than 200°C at a mine in Madagascar.”
With their excessive capacity, GEHO® pumps transport bauxite or iron ore over tons of of kilometres, offering some of the price efficient and sustainable switch methods obtainable to the mining trade. These pumps have also performed an integral function within the success of a Weir Minerals paste solution at Finland’s largest open pit mine. Yara’s Siilinjärvi mine uses GEHO® pumps to move tailings from the plant, achieving the mandatory seashore slope on its tailings facility to satisfy its life-of-mine strategy.
Backfilling is a vital methodology for mining to realize safety 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 material – measuring 70% solids by weight – again into the mine’s worked out areas.
In the context of deep mines, GEHO® pumps present an efficient and dependable way of dewatering from nice depths, instead of utilizing multiple smaller pumps to transfer water to floor. The powerful GEHO® pump range can do this by pumping from the bottom of a mine to the surface in just one lift – even over kilometres.
“Apart from the fee effectiveness of this answer, an essential benefit is that it reduces the chance of 1 pump in a pumping chain failing, and disrupting the whole dewatering function,” he says. “It also reduces the fee and maintenance requirements of getting multiple pumping stations at totally different ranges throughout the mine.”
The status of GEHO® pumps has additionally been built on their reliability, he explains. This has resulted from Weir Minerals’ ongoing research and development into its pumps’ wear components. This course of is predicated on an in-depth understanding of the entire pumping system during which the pump operates.
“Taking under consideration how our pumps interact with these systems, we focus on key aspects of the pumps such because the diaphragm and propelling liquid system,” he says. The propelling liquid provides the barrier between the piston and the diaphragm ensuring that all the shifting parts transfer in oil and never slurry.
He emphasises the significance of diaphragm dynamics and the want to management the amount of propelling liquid within the chamber. This is done by way of the PLC control, to ensure that the diaphragm runs in the proper place.
“Rubber is good at bending, but when it stretches it could tear,” he says. “ เกจวัดแรงอัดกระบอกสูบ is to extend the replacement intervals between diaphragm replacements, helping mines to scale back both their downtime and their whole value of ownership.”
The monitoring of GEHO® pumps’ operation is conducted by way of digital know-how so that operators can keep abreast – in actual 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 potentialities for transferring coarse ore to the floor from deep in a mine – as a less expensive option to conventional hoisting strategies.
“Vital to all our GEHO pump options is the Weir Minerals’ world service community, making certain that wherever our pumps are operating there will be an experienced local service crew to support them,” he concludes.
