Qdos 30 pumps boost process efficiency by providing accurate, linear and repeatable flow performance from 0.002 to 8.0 gal per hour 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. Advanced control features include fluid level monitoring, fluid recovery, line priming and intuitive flow calibration.
