Watson-Marlow unveils newest chemical metering pump

The Watson-Marlow Fluid Technology Group (WMFTG) has launched the Qdos Conveying Wave Technology (CWT) pump which extends the capabilities of peristaltic pump technology and offers longer service life than conventional tube-based designs.
Qdos CWT pumps achieve their peristaltic action by operating a fluid contact component that offers the identical fundamental perform as the tube of a conventional peristaltic pump. As well because the elimination of vapour locking, the component delivers steady, reliable performance, even with fluctuations in ambient temperature and stress.
To achieve the peristaltic pumping motion, the CWT pump head incorporates an EPDM component quite than a tube, which acts towards a PEEK observe. The ensuing fluid contact element is subjected to very low stress levels, allowing the Qdos CWT to supply an extended service life.
เพรสเชอร์เกจ provide high levels of chemical dosing accuracy in water remedy purposes. The pumps introduce chemical compounds, together with sodium hypochlorite for post-chlorination cycles, with out the need to overdose. The sealed CWT pump head delivers correct, linear and repeatable circulate and could be very secure because it minimises operator publicity to chemicals.
