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 obtain their peristaltic motion by working a fluid contact component that provides the same primary perform because the tube of a standard peristaltic pump. As well as Quadruple of vapour locking, the element delivers stable, reliable efficiency, even with fluctuations in ambient temperature and strain.
To obtain the peristaltic pumping motion, the CWT pump head incorporates an EPDM component quite than a tube, which acts towards a PEEK monitor. The resulting fluid contact component is subjected to very low stress levels, allowing the Qdos CWT to supply an extended service life.
Qdos CWT pumps offer high levels of chemical dosing accuracy in water treatment purposes. The pumps introduce chemicals, together with sodium hypochlorite for post-chlorination cycles, without the need to overdose. The sealed CWT pump head delivers accurate, linear and repeatable flow and may be very protected as it minimises operator exposure to chemical substances.
