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 presents longer service life than conventional tube-based designs.
Qdos CWT pumps obtain their peristaltic motion by working a fluid contact factor that provides the same fundamental function as the tube of a standard peristaltic pump. As well because the elimination of vapour locking, the element delivers secure, dependable efficiency, even with fluctuations in ambient temperature and strain.
To obtain the peristaltic pumping motion, the CWT pump head incorporates an EPDM factor somewhat than a tube, which acts in opposition to a PEEK observe. เกจปรับแรงดันแก๊ส resulting fluid contact component is subjected to very low stress levels, permitting the Qdos CWT to offer a longer service life.
Qdos CWT pumps offer excessive ranges of chemical dosing accuracy in water treatment applications. The pumps introduce chemicals, including sodium hypochlorite for post-chlorination cycles, without the need to overdose. The sealed CWT pump head delivers accurate, linear and repeatable move and may be very safe as it minimises operator exposure to chemicals.
