Watson-Marlow unveils latest 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 expertise and offers longer service life than conventional tube-based designs.
Qdos CWT pumps achieve their peristaltic action by operating a fluid contact element that gives the identical basic function because the tube of a standard peristaltic pump. As well as the elimination of vapour locking, the element delivers steady, dependable efficiency, even with fluctuations in ambient temperature and stress.
To obtain เกรดวัดแรงดัน pumping action, the CWT pump head incorporates an EPDM component quite than a tube, which acts in opposition to a PEEK observe. The resulting fluid contact element is subjected to very low stress levels, permitting the Qdos CWT to offer an extended service life.
Qdos CWT pumps offer excessive ranges of chemical dosing accuracy in water treatment 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 flow and could be very secure as it minimises operator publicity to chemical substances.
