Positive displacement pumps for the chemical industry

The chemical industry places high demands on pumping equipment. Any interruption in production or accidental spillage of fluid can be costly and cause serious health and safety risks. Watson-Marlow peristaltic pumps ensure safety, reliability and performance through:

  • Total fluid containment
  • Dry-running and self-priming capability
  • Cut chemical cost through higher accuracy metering
  • Simple drop-in installation eliminates ancillary equipment 
  • Long maintenance intervals, reducing the impact of process downtime
  • Lowering the overall cost of ownership

Our positive displacement pumps are designed to handle difficult, abrasive, corrosive and gaseous fluids. The only part to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely.

Precise metering of flow rates from microlitres per minute to 108 cubic metres per hour, with consistent accuracy of up to ± 0.5% ensures economical use of expensive chemicals and optimised system performance.
