Qdos 30 pumps boost process efficiency by providing accurate, linear, and repeatable flow performance from 0.002 to 8 gal/h at 100 psi (7 bar), 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, are 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.
Qdos 30 pumps feature Watson-Marlow’s ReNu pump head technology. Quick and easy pump head removal and replacement minimizes process downtime and requires no tools, training or technicians. The pump head can be configured on the left or right, making it ideal for installation 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-in. TFT color display, providing the status indication. The keypad and display are positioned for easy access, along with input and output connections.
The premium model in the range is the Qdos 30 Universal+. The pump response to the 4-20mA input signal is fully configurable, and a 4-20mA output and alarm output is available. Applications for Qdos 30 include disinfection and pH adjustment of drinking water and industrial process water; flocculation; industrial cooling water preparation; and reagent dosing in mineral processing, to name a few.
