Watson-Marlow has introduced its new Qdos 30 pump range. The chemical metering system eliminates ancillary equipment, enhances productivity, and reduces chemical waste through more accurate, linear, and repeatable metering than typical solenoid or stepper driven diaphragm metering pumps. The pumps deliver 5,000:1 flow from 0.002 to 8.0 gph at 100 psi while integrating easily through IP66 manual, analog, and PROFIBUS control options. Featuring patented ReNu pumphead technology, the pumps are fully sealed for safe, tool-free maintenance. Watson-Marlow Pumps Groupwww.wmpg.com
