The Watson-Marlow Fluid Technology Group (WMFTG) has launched the Qdos Conveying Wave Technology (CWT) pump which extends the capabilities of peristaltic pump know-how and offers longer service life than conventional tube-based designs.
ไดอะแฟรม achieve their peristaltic action by operating a fluid contact factor that offers the identical fundamental operate as the tube of a traditional peristaltic pump. As properly as the elimination of vapour locking, the component delivers steady, reliable efficiency, even with fluctuations in ambient temperature and stress.
To achieve the peristaltic pumping action, the CWT pump head incorporates an EPDM component quite than a tube, which acts against a PEEK track. The resulting fluid contact element is subjected to very low stress ranges, allowing the Qdos CWT to offer an extended service life.
Qdos CWT pumps provide excessive ranges of chemical dosing accuracy in water remedy purposes. The pumps introduce chemical compounds, including sodium hypochlorite for post-chlorination cycles, with out the necessity to overdose. The sealed CWT pump head delivers correct, linear and repeatable circulate and is very safe because it minimises operator exposure to chemical substances.
