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 technology and offers longer service life than traditional tube-based designs.
Qdos CWT pumps obtain their peristaltic motion by working a fluid contact element that offers the identical primary function because the tube of a conventional peristaltic pump. As well as the elimination of vapour locking, the component delivers secure, dependable performance, even with fluctuations in ambient temperature and pressure.
To achieve the peristaltic pumping action, the CWT pump head incorporates an EPDM element somewhat than a tube, which acts in opposition to a PEEK observe. The resulting fluid contact factor is subjected to very low stress levels, allowing the Qdos CWT to offer a longer service life.
Qdos CWT pumps offer high ranges of chemical dosing accuracy in water remedy applications. เกจวัดแรงดัน4นิ้วราคา introduce chemical compounds, including sodium hypochlorite for post-chlorination cycles, with out the need to overdose. The sealed CWT pump head delivers accurate, linear and repeatable flow and may be very protected as it minimises operator exposure to chemical compounds.
