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 know-how and provides longer service life than conventional tube-based designs.
Qdos CWT pumps obtain their peristaltic motion by working a fluid contact factor that offers the identical basic perform because the tube of a standard peristaltic pump. As properly as the elimination of vapour locking, the element delivers steady, dependable efficiency, even with fluctuations in ambient temperature and pressure.
To achieve the peristaltic pumping motion, the CWT pump head incorporates an EPDM component somewhat than a tube, which acts against a PEEK track. เกจวัดแก๊ส resulting fluid contact element is subjected to very low stress ranges, allowing the Qdos CWT to offer an extended service life.
Qdos CWT pumps offer high levels of chemical dosing accuracy in water therapy purposes. The pumps introduce chemical substances, together with sodium hypochlorite for post-chlorination cycles, without the need to overdose. The sealed CWT pump head delivers correct, linear and repeatable circulate and is very secure as it minimises operator publicity to chemical substances.
