Bredel’s heavy-duty SPX thickener underflow pump is designed for challenging mining applications and reliably handles a variety of harsh materials, including abrasive heavy metal slurries, corrosive cyanide, copper sulfate and methylcellulose. With flow-rates up to 350 GPM and pressures to 232 PSI, Bredel’s sealless SPX hose pumps can handle the most difficult applications and the harshest environments. 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 impellers, liners or mechanical seals to replace, no check valves to clog and no rotors and stators to wear out. In addition, millions of gallons of water can be saved as our hose pumps can handle high solid contents compared to centrifugal type pumps plus there is no need for mechanical seal flush water.
