    Optimising chemical dosing

    Discover six factors to consider in chemical dosing to achieve the best performance in onsite wastewater treatment.

Dosing pumps ensure accuracy and containment in chemical metering

The Qdos range of peristaltic chemical metering and dosing pumps cut costs through higher precision metering, with an accuracy of ±1% and repeatability of ±0.5% in dosing.

Qdos metering and dosing pumps minimise chemical consumption for applications in water and wastewater treatment, industrial process fluids, industrial effluent, mining and mineral processing, and for chemical applications in food and beverage.

Industry leading ReNu and CWT pumphead technology is at the core of the Qdos pump. This ensures the delivery of accurate and repeatable flow for fluids of wide ranging viscosities.

ReNu and CWT pumpheads provide accurate, linear and repeatable low pulse flow under varying process conditions.

Diaphragm metering pumps require high maintenance ancillaries to function. Qdos peristaltic chemical metering and dosing pumps eliminate this equipment while maintaining accurate, linear and repeatable metering for all process conditions.

Qdos metering and dosing pumps have a wide range of communication and connection options (PROFIBUS, EtherNet/IP™ and PROFINET).

There are six pumps in the Qdos range—20, 30, 60, 120, CWT and H-FLO—to meet your chemical metering and dosing requirements.

Common applications

  • Disinfectants
  • Coagulants
  • Flocculants
  • Acids/alkalis
  • Mining reagents
  • Surfactants
  • Cuts chemical cost through higher accuracy metering (±1%)
  • Simple drop-in installation eliminates ancillary equipment
  • Simple maintenance with single, no-tools, component replacement
  • Valveless design of pump reduces the possibility of pump blockages from fluids such as ferric chloride
  • Ability to run dry (and can also handle gaseous fluids such as sodium hypochlorite)
  • Suction lift of up to 9 m means the Qdos range is ideal for sampling applications
  • No backpressure valves, pulsation dampener, degassing valves, foot valves, strainers or float switches
