Watson-Marlow Bredel, the leading manufacturer of peristaltic pumps, announces the heavy-duty SPX underflow thickener pump, ideal for processing challenging mining applications. The SPX reliably handles a variety of harsh materials, including abrasive heavy metal slurries and corrosive cyanide, copper sulfate and methylcellulose.
Unlike conventional pumps, the SPX handles the thickener underflow and various metallurgical acid slurries typically used in mining operations without damage to the working parts of the pump. Peristaltic hose pumps are virtually maintenance free with no expensive seals to replace, no check valves to clog, and no rotors and stators to wear out.
Every Watson-Marlow Bredel peristaltic pump is an inherent metering pump with repeatability at 99.5%. Many models include integral digital drives and displays in washdown enclosures. These self-priming pumps accommodate flow rates from 0.1 microliter to 80 cubic metres per hour, and are extremely durable, withstanding pressures up to 16 bar (232 psi). There are no internal universal joints, valves, dead corners, or glands to impede flow and these pumps are reversible for back-flushing lines. They can also run dry indefinitely without damage and provide up to a 9m (30’) suction lift.
