Watson-Marlow Bredel offers the heavy-duty SPX pump for challenging environmental applications. The SPX handles a variety of harsh materials-such as sludge and abrasive slurries-with little maintenance required. Peristaltic hose pumps come with no expensive seals to replace, no check valves to clog, and no rotors and stators to wear out. With the self-loading design, replacement is quick and easy. Unlike other pump types, the highly abrasive nature of lime slurries does not affect pump life.
