PUMPS AND PIPELINES
With the new range , Weir Minerals offers robust and high performing mobile dewatering pump packages suitable for sites with variable conditions , including applications where liquids may contain high percentages of solids to be transported or acidic conditions with low pH values , it said .
“ Not only versatile and highly mobile , the Multiflo LF is engineered for efficiency with a proven , enclosed impeller design and leading-edge materials that dramatically reduce total cost of ownership ,” Weir added .
The Multiflo LF pump is available in different configurations to meet the varied demands of dewatering applications around the world . It can be supplied with a portable trailer , or as skidmounted packages with diesel engines ( Tier 3 & Tier 4F rated engine emissions ) or electric motor drive options .
“ No matter the configuration , the Multiflo LF pump range provides a dependable pumping solution with flow rates ranging from 100 cu . m / h to 3,200 cu . m / h and discharge heads of 10 m to 210 m ,” Weir said .
Ian Ross , Global Product Manager for
Weir Minerals , in late 2020 , launched a new mobile Multiflo ® LF pump range featuring trailer and skid-mounted pumps specifically designed to handle liquids ranging from water to sewage and sludge
Dewatering Solutions at Weir Minerals , said : “ The new Multiflo LF range features a selection of dewatering pump package that , compared to similar pumps on the market , reduce total cost of ownership through lower energy requirements .”
The pump features a hydraulically superior enclosed impeller design and larger diameter
pump shafts that allow the Multiflo LF to efficiently handle large solids while reducing operational and maintenance costs , according to the company . This is achieved through the advanced , high efficiency pump-end that requires less energy to process fluids , operates under reduced power requirements and consumes less fuel or electricity .
The enclosed impeller is further supported by a stout bearing frame and large diameter shaft that is less prone to deflection during cavitation , Weir says .
“ The Multiflo LF pump range is more forgiving than similar pumps on the market , and the design is proven to result in fewer seal failures and far fewer instances of shaft breakage in extreme conditions ,” the company added .
Ross continued : “ With this range , we deliver a complete dewatering pump package , with compressed delivery times , that can withstand almost anything , including misapplication due to improper pump selection . With the high-head Multiflo LF pumps , the double pump volute equalises internal pressure to eliminate radial thrust , which helps prevent both seals failure and shaft breakage .”
