Watson-Marlow showcases latest chemical metering pump

news item image
Watson-Marlow Fluid Technology Group has unveiled its Qdos chemical metering pumps that extends the capabilities of peristaltic pump technology and offers longer service life than traditional tube-based designs.
Qdos CWT pumps also offers important advantages in water treatment applications.
Users users will benefit from superior accuracy in chemical metering and dosing tasks, and the elimination of expensive ancillary equipment.
The pumps achieve their peristaltic action by operating a unique fluid contact element that, in effect, 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 pump head 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.
Qdos CWT pumps offer outstanding chemical dosing accuracy in water treatment applications.
The pumps introduce chemicals – including sodium hypochlorite for post-chlorination cycles – without the need to overdose, thus delivering consistently high accuracy for the life of the pump.
