Weir launches its WARMAN® SHW-XTR heavy-duty submersible slurry pump
Weir, a mining technology company, has redesigned its market-leading heavy-duty submersible slurry pump to deliver reliable performance in the harshest slurry environments.
Weir has made several design improvements to address the operational challenges miners face in submersible pumping applications.
The WARMAN® SHW-XTR heavy-duty submersible slurry pump uses a larger shaft and heavy-duty bearings to keep everything stable, run smoothly, and avoid motor failure from shaft deflection.
Weir has also raised the strainer off the ground and added protective legs to shield it from tools, debris, and other job site hazards.
To prevent fluid from entering the motor, Weir has developed a custom double mechanical seal with a pressure-balanced oil chamber that keeps water out and extends the life of the motor.
In line with Weir’s commitment to reducing the environmental impact of its products, the WARMAN® SHW-XTR pump uses a glycol-based cooling system that does not waste water. Its simplified design and standard materials reduce waste, and the biodegradable oil in the seal helps protect the environment in case of a leak.
Ian Ross, Weir Global Product Manager, Dewatering Solutions, said: "We’re fortunate to be redesigning this pump from a position of strength. The legacy WARMAN® SHW pump has been a mainstay in demanding applications in mining operations all over the world. Its hydraulics are trusted throughout the industry, which is why we’ve preserved these design elements and focused on making improvements elsewhere.
"We wanted to make the pump easier to maintain, which is why the WARMAN® SHW-XTR pump has fewer components and a smarter design. This will ensure it is easier to maintain and will also reduce the need for a large parts inventory.
"Two of the key challenges across the mining industry today are longer lead times and higher costs, so it was important that these factors informed the decision we made. As a result, the WARMAN® SHW-XTR pump is a standardised product, meaning faster delivery and better availability of spare parts."*

Papua New Guinea Extends Woodlark Mining Lease
Papua New Guinea’s government has thrown its weight behind Geopacific Resources Ltd., granting the company more time to develop its flagship Woodlark Gold Project in Milne Bay Province.
Mining Minister Rainbo Paita has approved an extension to Condition 7 (ii) of Mining Lease 508, which hosts the project, pushing the deadline to complete construction and commissioning of the mine to 5 October 2027. The lease itself runs until July 2034.
For Geopacific, the decision offers breathing space and certainty as it works through financing, environmental approvals, and a major drilling campaign ahead of delivering a definitive feasibility study later this year.
“As PNG celebrates 50 years of independence, we acknowledge this significant national milestone and commend the Government and people of PNG,” said Geopacific Chief Executive James Fox.
“We also recognise the leadership of the Minister for Mining and the team at the Mineral Resources Authority in approving our application to extend ML508 C7(ii),” he added.
The company recently submitted an environmental permit amendment request and supporting assessment report to the Conservation and Environment Protection Authority, aimed at reflecting project improvements in the updated feasibility study.
Fox said the extension provides “the flexibility and certainty needed to align the timing of project construction with the DFS and our exploration success,” describing it as both an endorsement of Woodlark’s potential and a sign of government support for responsible mine development.
The Woodlark project, which contains an estimated 1.67 million ounces of gold, is seen as a potential new engine of economic activity for Papua New Guinea. With drilling delivering encouraging results and government backing firming up, Geopacific hopes the project can soon shift from planning into reality.
Earlier, Australian-listed gold producer St Barbara Ltd has become a substantial shareholder in Geopacific Resources Ltd after acquiring a 14.4% strategic interest, strengthening ties between two companies with deep connections to Papua New Guinea’s mining sector.
The deal, completed through a transaction with Patronus Resources Ltd, saw St Barbara acquire 458.6 million Geopacific shares in exchange for returning 158.1 million Patronus shares. As a result, St Barbara now holds a 14.4% stake in Geopacific, while Patronus retains an interest of around 41 million shares.
