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.
Qdos CWT pumps obtain their peristaltic action by operating a fluid contact component that gives the identical basic operate because the tube of a traditional peristaltic pump. As well 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 somewhat than a tube, which acts against a PEEK observe. The ensuing fluid contact element is subjected to very low stress levels, permitting the Qdos CWT to offer an extended service life.
Qdos CWT pumps provide high levels of chemical dosing accuracy in water treatment applications. The pumps introduce chemical compounds, together with sodium hypochlorite for post-chlorination cycles, without the want to overdose. เกจวัดแรงดันออกซิเจนราคา sealed CWT pump head delivers correct, linear and repeatable circulate and may be very secure because it minimises operator exposure to chemical substances.
