Weir Minerals launch Multiflo LF pump range

Weir Minerals' Multiflo LF dewatering pump

New trailer and skid-mounted diesel and electric units expand mobile dewatering pump offering

WEIR Minerals have launched the new mobile Multiflo LF pump range, featuring trailer- and skid-mounted pumps specifically designed to handle liquids ranging from water to sewage and sludge.

With their new range, Weir Minerals say they are able to offer 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.

 

Versatile and highly mobile, the Multiflo LF is engineered for efficiency with a proven enclosed impeller design and leading-edge materials that are designed to significantly reduce total cost of ownership.

Available in different configurations to meet the varied demands of dewatering applications around the world, Multiflo LF pumps can be supplied with a portable trailer or as skid-mounted packages with diesel engine (T3 and T4F rated engine emissions) or electric motor drive options, all providing dependable pumping solutions with flow rates ranging from 100 cubic metres per hour to 3,200 cubic metres per hour and discharge heads from 10m to 210m.

‘The new Multiflo LF range features a selection of dewatering pump packages that, compared with similar pumps on the market, reduce total cost of ownership through lower energy requirements,’ commented Ian Ross, global product manager for dewatering solutions at Weir Minerals.

With a hydraulically superior enclosed impeller design and larger diameter pump-shaft, the Multiflo LF pumps are able to efficiently handle large solids while reducing operational and maintenance costs. This is achieved through an advanced, high-efficiency pump end that requires less energy to process fluids, operates under reduced power requirements and, in turn, consumes less fuel (litres/h) or electricity (kW/h). 

The enclosed impeller is further supported by a stout bearing frame and large-diameter shaft that is less prone to deflection during cavitation. As a result, the Multiflo LF pump range is said to be 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.

‘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,’ Mr Ross explained. ‘With the high-head Multiflo LF pumps, the double pump volute equalizes internal pressure to eliminate radial thrust, which helps prevent both seals failure and shaft breakage.’

The innovative engineering and efficient fluid handling of the Multiflo LF are complemented by the heavy-duty wear-resistant materials of construction that include cast steel and cast CD4MCu stainless steel for enhanced abrasion and corrosion resistance. Casting the pumps from steel creates a more robust pump and also promotes extended wear life, with the possibility of weld repairing the casing should a problem develop.
