Weir launch Warman SHW-XTR heavy-duty submersible
Heavy-duty submersible slurry pump redesigned for reliable performance in harshest environments
WEIR have redesigned their heavy-duty submersible slurry pump to deliver reliable performance in the harshest slurry environments. Several design improvements have been made to address the operational challenges faced in submersible pumping applications.
The Warman SHW-XTR heavy-duty submersible uses a larger shaft and heavy-duty bearings to keep everything stable and running smoothly, and to avoid motor failure from shaft deflection.
Weir have 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 have developed a custom double mechanical seal with a pressure-balanced oil chamber that keeps water out and extends the life of the motor.
Also, in line with Weir’s commitment to reduce the environmental impact of their 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, global product manager - dewatering solutions at Weir, 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 all over the world. Its hydraulics are trusted throughout 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 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 standardized product, meaning faster delivery and better availability of spare parts.’
