Chemistry & process industry

Stainless steel chemical pumps are used in the chemical and process industries for the safe and precise pumping of chemical media. The gear pumps from Linn-Pumpen are suitable for neutral to aggressive liquids and offer high resistance to chemical loads. Thanks to their precise pumping characteristics, they meet the technical requirements of modern process plants.

 

Typical applications

  • Transfer and dosing in production and pilot plants
  • Circulation circuits in reactors and mixers
  • Feeding filters, heat exchangers and apparatus
  • Media containing solvents (observe choice of material and seal)
  • Aqueous, low to non-lubricating media

Technical requirements

  • Medium: corrosiveness, viscosity, solvent content, traces of solids if applicable
  • Define temperature range and viscosity window
  • Select suitable seals (e.g. FKM, EPDM, PTFE; mechanical seal depending on medium)
  • Materials: Stainless steel for wetted parts; PEEK gears for aqueous/non-lubricating applications
  • Speed control via FI with variable target volume flows
