New pump delivers major advance in long-life chemical metering

摘要

Watson-Marlow Fluid Technology Group (WMFTG) is unveiling the next performance level in its range of industry-leading Qdos chemical metering pumps. Qdos® Conveying Wave Technology (CWT™) extends the capabilities of peristaltic pump technology and offers longer service life than traditional tube-based designs. CWT™ also offers important advantages in water treatment applications; users will benefit from superior accuracy in chemical metering and dosing tasks, and the elimination of expensive ancillary equipment. Qdos® CWT™ pumps achieve their peristaltic action by operating a unique fluid contact element that, in effect, offers the same basic function as the tube of a conventional peristaltic pump. As well as the elimination of vapour locking, the element delivers stable, reliable performance, even with fluctuations in ambient temperature and pressure. Furthermore, the robust mechanical design provides consistently high accuracy for the life of the pump.
