Watson-Marlow will showcase its revolutionary Qdos 30 pump range at WEFTEC 2012 on Oct. 1 - 3 in Booth 2837, Hall D at the New Orleans Morial Convention Center. Developed in response to extensive industrial customer feedback for improved chemical metering, the Qdos 30 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 Qdos 30 delivers an unrivaled 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, Qdos 30 is fully sealed for safe, tool-free maintenance. Qdos 30 pumps boost process efficiency by providing accurate, linear and repeatable flow performance from 0.002 to 8.0 GPH at 100 PSI, even when metering difficult fluids when pressure, viscosity and solids content vary. There are no seals or valves in the flow path to clog, leak or corrode. This means that slurries and fluids that are caustic, abrasive, viscous, shear-sensitive, gaseous or contain suspended solids, can be safely and securely handled. Advanced control features include fluid level monitoring, fluid recovery, line priming and intuitive flow calibration.
