Watson-Marlow Pumps’ Qdos 30 pump range has been designed to eliminate ancillary equipment and reduce chemical waste through more accurate, linear and repeatable metering than typical solenoid or stepper driven diaphragm metering pumps. The Qdos 30 delivers a 5,000:1 flow from 0.002 to 8.0 GPH at 100 PSI while integrating through IP66 manual, analog and PROFIBUS control options. Featuring 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 fluids that are caustic, abrasive, viscous, shear-sensitive, gaseous, slurries 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.
Developed in response to extensive customer feedback, Qdos 30 pumps feature Watson-Marlow’s ReNu pumphead technology. Quick pumphead removal and replacement minimizes process downtime and requires no specialist tools, training or technicians. The pumphead can be configured on the left or right, making it suitable for installing in restricted environments or on skids, while its sealed design and fluid recovery eliminate wastage and ensures operator safety. Operation is intuitive via a menu-driven interface with a 3.5-inch TFT color display, providing high-visibility status indication.
