Wide range of applications

  • Chemical industry: Promotion of acids and bases that have little or no lubricating effect.
  • Pharmaceutical industry: Transport of non-lubricating solvents or other sensitive liquids.
  • Water treatment: Dosing and delivery of chemicals that offer little lubrication.

Conveying media

The pumps of the Series E/FLM PEEK are suitable for pumping corrosive liquids, emulsions, pastes and oils. Conveying chemically aggressive fluids without abrasive components.
E/F Pumps The pumped media must guarantee a minimum level of lubrication
E/F -PEEK pumps for low to non-lubricating media

Shaft seals

  • Rotary shaft seal
  • Radial shaft seal with thrust bearing
  • Double rotary shaft seal
  • Mechanical seal
  • Magnetic coupling
