Weir Minerals has launched its new mobile Multiflo® LF pump range featuring trailer and skid-mounted pumps specifically designed to handle liquids ranging from water, to sewage and sludge.
The launch follows successful installations across North and South America, South Africa, and Kazakhstan.
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 skid-mounted packages with diesel engines (T3 & T4F 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 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, operating under reduced power requirements, and, in turn, consuming 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.”
The Multiflo LF comes with heavy-duty wear-resistant materials of construction that include cast steel and cast CD4MCu stainless steel for enhanced abrasion and corrosion resistance, Weir says. 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, according to the company.
Ross concluded: “Weir Minerals prioritises partnering with our customers. We’re right there on site from the beginning, from specification to delivery, installation, commissioning, training, and maintenance. We know the Multiflo LF performs, and we take the time to make sure it’s performing to our customers’ requirements.”
