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 expertise and provides longer service life than traditional tube-based designs.
Qdos CWT pumps achieve their peristaltic motion by working a fluid contact element that gives the same basic function as the tube of a standard peristaltic pump. As nicely because the elimination of vapour locking, the element delivers stable, reliable efficiency, even with fluctuations in ambient temperature and stress.
To achieve the peristaltic pumping action, the CWT pump head incorporates an EPDM element quite than a tube, which acts in opposition to a PEEK track. 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 excessive levels of chemical dosing accuracy in water treatment functions. เครื่องมือที่ใช้วัดความดันเลือด introduce chemicals, 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 could be very protected because it minimises operator exposure to chemical compounds.
