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 technology and offers longer service life than traditional tube-based designs.
Qdos CWT pumps achieve their peristaltic motion by working a fluid contact component that gives the same basic perform as the tube of a conventional peristaltic pump. As nicely because the elimination of vapour locking, the element delivers steady, dependable performance, even with fluctuations in ambient temperature and strain.
To obtain spmk700 pumping motion, the CWT pump head incorporates an EPDM factor rather than a tube, which acts in opposition to a PEEK monitor. The resulting fluid contact component is subjected to very low stress ranges, permitting the Qdos CWT to offer an extended service life.
Qdos CWT pumps offer high ranges of chemical dosing accuracy in water therapy 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 move and may be very safe as it minimises operator publicity to chemicals.
