Atlas Copco has launched a next-generation electric submersible dewatering pump, the WEDA D95, incorporating state-of-the-art Wear Deflector technology.
The robust and reliable pump delivers a best-in-class performance over a longer lifetime than comparable pumps in heavily abrasive environments such as mining, tunnelling and construction, and enables operators to improve their sustainability and productivity.
WEDA D95 has a power rating of 37–43 kilowatts (kW) and is the latest pump in the WEDA D drainage range to feature the innovative Wear Deflector technology designed to minimise wear and provide consistent performance over a longer operating life.
Features such as a high chrome wear resistant impeller combined with solid-redirecting auxiliary vanes contribute towards its performance. The pump also features re-adjustable hydraulics which allow the pump to be simply realigned to compensate for any wear, thus prolonging its life.
All these elements have a significant positive impact on the overall operational productivity, meaning users can achieve a lower total cost of ownership.
“There are often many suspended solids in harsh applications which can cause excessive abrasion and wear to the internal workings of the pump,” Atlas Copco Power and Flow product marketing manager – submersible pumps Bart Duijvelaar said.
“At Atlas Copco, we are driven by innovation, and so we have taken the fundamental design of the drainage pump back to the drawing board. We have optimised the hydraulic design using computational fluid dynamics and applied 21st century manufacturing techniques combined with decades of experience to produce this new long-lasting and reliable pump.”
The pump has also been built with maintenance and serviceability front of mind. Thanks to the clever design, users can also carry out inspection and maintenance on site themselves and reduce downtime and associated costs. For example, the mechanical seal is a unique stainless-steel single cartridge, rather than many separate components, and so it is easy to replace in one piece.
For Atlas Copco Power and Flow achieving a more sustainable future is crucial. Therefore, facilitating the repairability of its pumps has been at the forefront of the design to ensure less time-consuming maintenance and best-in-class service support. It gives a second life to these pumps with increased uptime.
WEDA D95 also features external oil inspection screws. Operators can easily access the screws to check the quality of the oil and the health status of the seal without having to dismantle the whole pump. This makes preventive maintenance easy so users can detect problems before they lead to failure.
Overall, with the ease of service, it is possible to readjust the pump to the original performance without changing many parts. The pump’s repairability prolongs the life of the pump, giving it a second life and contributing towards a more sustainable future.
Additionally, the pumps in the D range are available with various accessories including different types of discharge connections, pump rafts and zinc anodes to provide extra corrosion resistance.
The new WEDA D95 pumps are backed by Atlas Copco’s service team and supported by a wide network of local dealers and technicians worldwide with readily available parts to help users keep their operations up and running to improve productivity.
With state-of-the-art manufacturing and 3D modelling tools, Atlas Copco is addressing product performance and technical challenges at the design stage. The WEDA D95 submersible pump is the latest example of a well-crafted and thoughtfully designed pump range, with more models expected in the company’s portfolio in the coming years.

AspenTech is providing intelligent digital solutions to the mining industry, helping reduce downtime and emissions while maximising asset performance.
Mobile and fixed equipment plant maintenance is one of the costliest parts of a mining operation. This stems from the fact that site operators typically rely on preventive maintenance schedules designed by the original equipment manufacturer.
But this system is too rigid to depend on, and can fail to account for variations in the use of equipment, different working environments and the effects of extreme weather. It’s the equivalent of ignoring the warning light in a car because it’s still got three months until the next service.
There is a better way of doing things, and it’s called prescriptive maintenance. AspenTech’s Aspen Mtell solution offers the mining industry exactly that.
Aspen Mtell is a predictive and prescriptive maintenance solution that uses machine learning to monitor equipment in real-time for imminent and future failures.
“Companies are facing increasing pressure to reduce their carbon footprint and improve operational efficiency in order to meet global climate targets,” senior industry marketing consultant for AspenTech, Brandon Richardson, told Australian Mining. “To deal with these challenges, many companies are turning to digitalisation solutions.
“AspenTech offers advanced digitalisation solutions specifically designed to assist companies in the mining industry to achieve their sustainability goals and improve operational efficiency, while also minimising costly environmental and safety risks.
“AspenTech’s asset performance management solutions provide a comprehensive suite of tools, including Aspen Mtell, to monitor and optimise performance of mining assets.”
By monitoring machine performance round-the-clock, the Mtell software can recognise patterns indicative of degradation and impending failure. These early warnings give site operators the chance to plan maintenance weeks – and sometimes months – ahead, rather than reactively working through equipment failures at the expense of time and money.
“The high costs associated with maintenance, repairs, and downtime can be a significant burden for mining companies,” Richardson said.
“AspenTech helps address these challenges by providing predictive maintenance solutions that can reduce downtime and maintenance costs.”
Aspen Mtell has been tried and tested in the field, and the results speak for themselves.
“A particular mining client was having difficulty predicting when maintenance was required on their trucks, resulting in frequent breakdowns and increased maintenance costs,” Richardson said.
“By implementing Aspen Mtell, the company was able to analyse sensor data from the trucks and develop predictive models called agents that could accurately forecast maintenance needs.
“This allowed the company to proactively schedule maintenance, reducing unplanned downtime and improving overall equipment reliability.”
Aspen Mtell is also making operations safer. In one instance, the software flagged a failure in a customer’s oil heater.
“In those types of industrial machines, a failure would have meant hot oil vaporising cold water, which would have caused a rapid steam explosion,” Richardson said.
“A failure would have had catastrophic safety implications, but thanks to Aspen Mtell, the site operator was able to take pre-emptive action and avoid an accident.”
Aspen Mtell pairs well with another AspenTech solution, known as advanced process control (APC). APC provides real-time control and optimisation of equipment, helping mining companies make their operations run as efficiently as possible.
“APC enables mining companies to optimise their production processes and reduce energy consumption,” Richardson said. “AspenTech APM and APC solutions help mining companies to make data-driven decisions that improve process efficiency, optimise production, and reduce environmental impact.
“The integration of AspenTech APM and APC solutions ensures that mining companies can achieve their sustainability objectives while remaining competitive in an uncertain economic environment.”
Energy efficiency and safety play a huge role in achieving environmental, social and governance (ESG) targets, meaning solutions like Aspen Mtell are vital for staying competitive in an evolving mining market.
And ESG targets are much more than just a peripheral consideration.
There is tangible value for mining companies in maintaining safe and responsible worksites, and in reducing emissions in line with the global push for net-zero.
Social and environmental practices are becoming essential for mining companies to secure a social license to operate. Demonstrating such responsibility helps project approvals go smoother, which directly translates to a faster timeline and profitability.
In this way, intelligent solutions like AspenTech APM and APC not only help keep expenses under control, but add real value for AspenTech’s mining industry clients.
“AspenTech is committed to helping its clients in the mining industry achieve sustainable, cost effective, and optimised operations,” Richardson said.
“The company has a network of experts of who can provide support and guidance throughout the implementation process, ensuring clients get the most out of their investment.”

By paying close attention to the sealing solution used in the gland area of slurry pumps, mining operators can increase productivity – and profitability.
Slurry pumps are the workhorses of mining operations, helping to efficiently transport ore in the form of slurry throughout the site. Unfortunately, they are also often one of the more trouble-prone parts of many plants, with the abrasive nature of mining slurries taking a high toll on pump components.
A particular stress point is the gland area, where mechanical seals or packing are used to prevent leakage. Sealing solutions that are of poor quality or that are ill-suited to the application at hand can greatly increase maintenance demands, and lead to unplanned stoppages and excessive water use.
Mining operators looking to increase the efficiency of their slurry pumps – and in turn the whole operation – should spend time analysing their slurry and choose a tailored sealing solution that can cope with the inherent stresses.
Some of the factors to consider when analysing the slurry include the hardness and abrasiveness of the slurry; the amount and weight of solids being carried; and the salinity, chemical composition and temperature of the slurry. These can all impact heavily on component wear.
Armed with this information, operators can make a more informed choice about what kind of features are required from a sealing solution, be it a mechanical seal or packing. While uptake of mechanical seals is varied across mining settings, they have the potential to extend time between maintenance intervals by up to four times compared to packing. However, a slightly higher level of training is required among maintenance staff.
How to choose the right seal and packing
So, what factors should be considered when choosing a mechanical seal?
A good seal should have a stationary sprung design with non-clogging springs and micro-polished dynamic O-ring surfaces. It should also have the flexibility to add erosion protection features, like polyurethane in applications where the slurry is extremely abrasive.
Additionally, a good mechanical seal should also be flexible enough to add support features to prolong operating life, such as quench/drain and flush. It should have line-to-line seal faces, and be designed with generous cross sections and a robust drive mechanism that can mount on hardened pump sleeves.
For packing, the yarn needs to be sufficiently strong to prevent the slurry from penetrating into the fibre. It should be woven in a manner that creates a torturous leak path.
The packing needs to be low friction for low energy consumption and to reduce any damage to the rotating shaft, despite the presence of slurry. It should also be flexible enough to transfer the axial energy into radial load and maintain a positive seal for prolonged periods. Thereby reducing the amount of follower adjustments required during the life of the packing.
In conclusion, slurry pumps play a crucial role in mining operations. By examining operating conditions and requirements and choosing an appropriate sealing solution, pump uptime can be increased, water consumption reduced, and high productivity maintained.

Lance Brett has been working in mechanical seals for over 35 years. Now a national product manager at Seal Innovations, he is excited to bring the new Heavy Duty Slurry Seals onto the market for Australian customers.
“We’re really pleased with the quality of these seals and how they stand up in terms of wear life and reliability,” he said.
“It perfectly complements the rest of our product range and offers new potential for our involvement in the mining and quarrying sectors.”
The role of a sealing application cannot be overlooked, especially in resources where they act to secure valuable materials while they are being processed. Slurry is formed when water combines with ferrous and non-ferrous raw material, such as rock and soil between 1mm and 25mm thick. In mining, there are several types of pumps used in the transport of large volumes of slurry to mineral processing plants, where it then undergoes a separation process.
The solids within slurry can often prove highly abrasive, contributing to the accelerated wear life of critical parts, including seals. This problem can be amplified in a hyper saline environment, which may cause crystallisation of material around the surface.
The new Heavy Duty Slurry Pump Seal from Seal Innovations can withstand the harshest operating environments, providing maximum seal life in mining, quarrying and dewatering applications. The abrasion resistant metal components, along with silicone carbide faces, create an open design which reduces flush water and product dilution.
“This seal unit has been specifically designed for handling slurry concentration of up to 40 per cent solids by weight,” Brett said.
“It is an incredibly robust construct mechanical seal which is best suited to rugged mining and quarrying environments. Differently to standard O-ring designs, it is a rotating assembly, offering accurate installation with no special tools required.”
What’s more, the smooth, elastomer-coated cone spring increases the product’s reliability with an even spring load to the seal’s faces. This ensures minimal wear or clogging, in operating pressures up to 300 psig (20.7 bar).
“We have introduced this product to fill a prominent need in the market for mining-suited slurry pump parts,” Brett said.
“It’s a really exciting addition to our portfolio of industry leading seal products, and we’re already taking it to some of our most valued customers as an upgrade solution on troublesome equipment.”
He adds that, in addition to a comprehensive catalogue of sealing products, the business also provides aftermarket engineering and repair services from some of their centrally located branches.
“We can repair and overhaul slurry pump units as well as seals from our workshop in Brisbane, and we can repair any type of slurry seal from our Melbourne workshop,” Brett said.
“Everything is repaired back to manufacturer specification, and thoroughly tested for performance before re-entering the field.”
Technicians from Seal Innovations regularly visit customer sites, utilising their comprehensive knowledge of seal engineering to carry out audits, training and installation services. In line with its motto – “keep industry moving” – the company strives to meet each customer’s unique requirements and offer a one-stop-shop for all sealing needs.
