Weir Minerals expands mobile dewatering pump range

World Coal,

Weir Minerals has 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 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. 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.

The Multiflo LF pump is available in different configurations to meet the varied demands of dewatering applications around the world. The Multiflo LF can be supplied with a portable trailer, or as skid-mounted packages with diesel engines (T3 and T4F rated engine emissions) or electric motors drive options. No matter the configuration, the Multiflo LF pump range provides a dependable pumping solution with flow rates ranging from 100 m3/h to 3200 m3/h and discharge heads of 10 m to 210 m.

Ian Ross, Global Product Manager for Dewatering Solutions at Weir Minerals, commented: “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 allows the Multiflo LF to efficiently handle large solids while reducing operational and maintenance costs. This is achieved through the advanced, high-efficiency pump-end that requires less energy to process fluids, operating under reduced power requirements, and in-turn consuming less fuel (LPH) 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. 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.

“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,” Ian Ross continued. “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.”

The 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 additionally promotes extended wear-life with the possibility of weld repairing the casing should a problem develop.
