Chemical metering and transfer

Peristaltic pumps that accurately pump abrasive chemicals such as lime slurry , powdered activated carbon (PAC), sodium hypochlorite (hypo), alum and other chemicals

Chemical metering and transfer requirements

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
