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 action by working a fluid contact element that offers the identical basic operate because the tube of a conventional peristaltic pump. As well because the elimination of vapour locking, the element delivers steady, dependable performance, even with fluctuations in ambient temperature and pressure.
To obtain the peristaltic pumping motion, the CWT pump head incorporates an EPDM factor somewhat than a tube, which acts towards a PEEK observe. The resulting fluid contact element is subjected to very low stress levels, allowing the Qdos CWT to offer a longer service life.
Qdos CWT pumps provide high levels of chemical dosing accuracy in water therapy purposes. เกจวัดแรงดันน้ำมันเครื่อง introduce chemical substances, together with sodium hypochlorite for post-chlorination cycles, without the want to overdose. The sealed CWT pump head delivers correct, linear and repeatable flow and is very protected as it minimises operator exposure to chemical compounds.
