Chemical metering for the wastewater industry - Water and Wastewater

Watson-Marlow`s tube pumps and hose pumps handle a broad range of chemical metering and transfers that destroy progressive cavity, lobe and diaphragm pumps.

Abrasive chemicals such as lime slurry , powdered activated carbon (PAC), sodium hypochlorite (hypo), alum and other chemicals wear metallic parts and rip through rotors, stators and seals of other pump types causing a maintenance nightmare.

Our positive displacement pumps provide consistent and reliable performance.  The features include:

  •  high pressure capability for chemical injection
  • metering accuracies to +/- 0.5% saving on expensive chemical usage
  • no ancillary equipment required
  • only one wearing part – the tube/hose
  • self-priming, dry running, no vapor locking
  • Lower total cost of ownership
    With peristaltic pumps the slurry is securely contained within the hose, only contacting the hose making maintenance a breeze.
