The Watson-Marlow Fluid Technology Group (WMFTG) has launched the Qdos Conveying Wave Technology (CWT) pump which extends the capabilities of peristaltic pump know-how and provides longer service life than traditional tube-based designs.
pressure gauge achieve their peristaltic motion by working a fluid contact factor that gives the identical primary operate because the tube of a traditional peristaltic pump. As nicely as the elimination of vapour locking, the factor delivers secure, dependable efficiency, even with fluctuations in ambient temperature and stress.
To achieve the peristaltic pumping action, the CWT pump head incorporates an EPDM factor quite than a tube, which acts in opposition to a PEEK observe. The resulting fluid contact component is subjected to very low stress ranges, allowing the Qdos CWT to supply an extended service life.
Qdos CWT pumps provide high ranges of chemical dosing accuracy in water remedy purposes. The pumps introduce chemical compounds, including sodium hypochlorite for post-chlorination cycles, with out the need to overdose. The sealed CWT pump head delivers correct, linear and repeatable circulate and could be very safe because it minimises operator publicity to chemicals.
