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 presents longer service life than conventional tube-based designs.
ไดอะแฟรม ซีล achieve their peristaltic motion by operating a fluid contact element that offers the same fundamental function because the tube of a traditional peristaltic pump. As properly as the elimination of vapour locking, the factor delivers steady, dependable efficiency, even with fluctuations in ambient temperature and pressure.
To obtain the peristaltic pumping action, the CWT pump head incorporates an EPDM element rather than a tube, which acts in opposition to a PEEK track. The resulting fluid contact component is subjected to very low stress ranges, permitting the Qdos CWT to supply a longer service life.
Qdos CWT pumps provide excessive levels of chemical dosing accuracy in water remedy applications. The pumps introduce chemical compounds, including sodium hypochlorite for post-chlorination cycles, without the need to overdose. The sealed CWT pump head delivers correct, linear and repeatable flow and is very protected as it minimises operator publicity to chemical substances.
