Qdos – innovative metering solution

Innovative Qdos metering pumps from Watson-Marlow Pumps are suitable for all applications in a variety of industries including paper and cardboard production where chemicals need to be metered with high accuracy and reliability. Odos pumps offer precise, linear and repeatable flows of up to 120 litres per hour at pressures up to 7 bar, irrespective of viscosity. Qdos pumps eliminate the need of ancillary equipment such as valves or pulsation dampeners. The only consumable part is the patented WatsonMarlow ReNu pumphead which can be replaced in a few minutes with no tools or special skills required. Thus, Qdos guarantees minimum maintenance compared to other metering pumps.

With high accuracy, Qdos significantly optimises the consumption of chemicals compared to other pump types. The contained pumphead design with integral leak detection guarantees operator safety. Intuitive operation is facilitated via a menu-driven interface featuring a 3.5" TFT colour display with high visibility status indication making pump calibration very easy.

Designed as a drop-in replacement for diaphragm pumps, Qdos is available in four different sizes and for manual operation through to PROFIBUS integration. All models are ideally suited for demanding tasks in process water purification and disinfection and metering of dye, anti-foam agents, retention agents, additives,  and reagents and chemicals.
