Peristaltic dosing and metering

Qdos metering pump

Delivering flow rates that remain constant right up to 7 bar Qdos peristaltic chemical metering pumps give users a unique advantage over diaphragm metering pumps.

Qdos pumps eliminate the need for ancillary equipment while ensuring accurate, linear and repeatable metering across all process conditions

  • Cut chemical cost through higher accuracy metering
  • Simple drop-in installation eliminates ancillary equipment
  • Reduced maintenance with single, no-tools, component replacement
  • Flow rates from 0.1 to 2,000 ml/min at up to 7 bar

Single-use pumps

Case Study - Watson-Marlow pump reduces chocolate flavour changes from hours to minutes

Devon-based Moo Free Ltd is taking advantage of a 530 series process pump from Watson-Marlow Fluid Technology Solutions (WMFTS) to optimise the manufacture of dairy-free, gluten-free vegan and organic chocolate products. Acquired as part of a production process redesign, the 530 pump is helping the company to reduce the time required for flavour changeovers from half a day to just five minutes.

Mr March commissioned the manufacture of a small stainless-steel hopper which sits above the Watson-Marlow 530UN/R2 pump to provide gravity feed for the flavouring.
