Watson-Marlow Fluid Technology Group (WMFTG) announces 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. It also offers superior accuracy in chemical metering and dosing tasks, and the elimination of expensive ancillary equipment. These 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. The element delivers stable, reliable performance, even with fluctuations in ambient temperature and pressure. The pumps introduce chemicals without the need to overdose, thus delivering consistently high accuracy for the life of the pump. The CWT range offers flowrates from 0.1 to 500 ml/min (16.9 oz/min) and up to 7 bar RMS pressure. Flow control is up to 5000:1 with ±1-percent accuracy. A three-year warranty is standard.
