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," Ross said.
"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," he added.
