Weir launches heavy-duty submersible slurry pump

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 uses a larger shaft than previous designs and heavy-duty bearings to keep everything stable, running smoothly and avoid motor failure from shaft deflection.  

Weir dewatering solutions global product manager Ian Ross says the legacy WARMAN SHW pump has been a mainstay in demanding applications in mining operations all over the world. 

“[The pump’s] hydraulics are trusted throughout the industry, which is why we’ve preserved these design elements and focused on making improvements elsewhere,” he said. 

Weir has also raised the strainer off the ground and added protective legs to shield it from tools, debris and other job site hazards.  

“We wanted to make the pump easier to maintain, which is why the WARMAN SHW-XTR pump has fewer components and a smarter design,” Mr Ross said.  

“This will ensure it is easier to maintain and will also reduce the need for a large parts inventory.” 

To prevent fluid entering the motor, the company has developed a custom double mechanical seal with a pressure balanced oil chamber that keeps water out and extends the life of the motor.  

“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,” Mr Ross said. 

“As a result, the WARMAN SHW-XTR pump is a standardised product, meaning faster delivery and better availability of spare parts.” 

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.
