Qdos goes to Watson-Marlow Fluid Technology

Watson-Marlow Fluid Technology Group (WMFTG) has unveiled the next performance level in its range of Qdos chemical metering pumps.
Qdos Conveying Wave Technology (CWT) extends the capabilities of peristaltic pump technology and offers longer service life than traditional tube-based designs.
CWT also offers important advantages in water treatment applications - users will benefit from superior accuracy in chemical metering and dosing tasks, and the elimination of expensive ancillary equipment.
Qdos CWT pumps achieve their peristaltic action by operating a unique fluid contact element that offers the same basic function as the tube of a conventional peristaltic pump. As well as the elimination of vapour locking, the element delivers stable, reliable performance, even with fluctuations in ambient temperature and pressure.
Furthermore, the robust mechanical design provides consistently high accuracy for the life of the pump.
To achieve the peristaltic pumping action, the CWT pumphead incorporates an EPDM element rather than a tube, which acts against a PEEK track.
The resulting fluid contact element is subjected to very low stress levels, meaning the Qdos CWT pump will deliver significantly longer service life than a traditional pump.
“This is an exciting launch for us,” said Martin Johnston, strategic business development director at WMFTG.
“Qdos CWT is the next level in high performance for our industry leading Qdos® range of chemical metering pumps.
“Our objective was to design a technology that delivers all the benefits of a traditional pump but with significantly longer service life than traditional tube designs. It’s clear from early user feedback that CWT will help to deliver operational efficiencies to a wide range of users.”
