BBA Pumps has introduced a new line of diesel driven bolt-on pump packages to cater to the mining market niche where there is no need for a complete skid and/or canopy, for which it has developed a sub-frame assembly. These units feature the BA or BA-C customer pump of choice coupled to a diesel engine, including the control panel, and mounted on a high quality, galvanised sub-frame. The frames can be customised with lifting bales or protection bars should these be required. These auto prime pumps have a capacity of 100 m3/h to a maximum of 1,750 m3/h and a head of up to a maximum of 250 mwc (25 bar).The units can be bolted onto any object or structure, offering “true bolt-on pumping power.” End-users only need to connect a fuel tank and the unit is operational. Using high efficiency pumps and state-of-the-art diesel engines, the units offer maximum performance at minimal cost, which the company says is fully in-sync with its stated philosophy of lowest cost of ownership. For example the BA-C250H45 D610 has a maximum flow of 1,500 m3/h, maximum pressure of 180 mwc, and a pump speed of 1,800 rpm. It has a ductile iron casing with 8 in discharge and 16 in suction connections. The pump is a closed impeller, stainless steel type, able to handle 60 mm solids and with a BBA MP100 priming system. The pumps weights 6.5 t and is power by a 709 bkW Caterpillar C32 ACERT engine. Duplex stainless steel design enables the pumps to handle advanced dewatering jobs in environments where pH levels are unpredictable and varying – from very acidic to very alkaline. Furthermore, Duplex also allows the pumps to be used in more abrasive applications as it will not “pit” like regular stainless steel. Duplex Stainless Steel is much more resistant to corrosion and much stronger.
