Weir has redesigned its market-leading heavy-duty submersible slurry pump to deliver reliable performance in the harshest slurry environments.
The Warman SHW-XTR heavy-duty submersible slurry pump, which addresses the operational challenges that miners face in submersible pumping applications, uses a larger shaft and heavy-duty bearings to keep everything stable, running 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 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 reduce the environmental impact of its products, the Warman SHW-XTR pump uses a glycol-based cooling system that doesn’t 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.
“We’re fortunate to be redesigning this pump from a position of strength,” said Ian Ross, Weir Global Product Manager, Dewatering Solutions. “The legacy Warman SHW pump has been a mainstay in demanding applications in mining operations all over the word. 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.”
