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 provides longer service life than conventional tube-based designs.
เครื่องมือตรวจวัดความดันเลือดเรียกว่า achieve their peristaltic motion by working a fluid contact element that offers the same fundamental perform because the tube of a standard peristaltic pump. As well because the elimination of vapour locking, the factor delivers secure, reliable performance, even with fluctuations in ambient temperature and stress.
To achieve the peristaltic pumping motion, the CWT pump head incorporates an EPDM element rather than a tube, which acts against a PEEK observe. The ensuing fluid contact element is subjected to very low stress ranges, permitting the Qdos CWT to supply a longer service life.
Qdos CWT pumps offer high levels of chemical dosing accuracy in water treatment applications. The pumps introduce chemical substances, together with sodium hypochlorite for post-chlorination cycles, without the necessity to overdose. The sealed CWT pump head delivers correct, linear and repeatable flow and could be very protected because it minimises operator exposure to chemical compounds.
