ET - Ceramic Lined Double Mechanical Seal Chemical Process Pump

Discover the benefits of the ET produced by CP here - The centrifugal pump lined with ceramic is ideal for corrosive and abrasive media.


Special features

  • Very well suited for solids.*
  • Ideal for corrosive and abrasive media.
  • Ceramic lining is abrasion, corrosion and diffusion-resistant and achieves high chemical resistance.


  • double or single mechanical seal
  • Futura Mik® double mechanical seal: ideal for fluids with high solids content and with tendency to crystallisation and/or polymerisation, completely metal free on pump side.
  • horizontal installation
  • nominal pressure PN 10
  • dirt-resistant open impeller
  • clearance of the impeller can be optimally adjusted from outside

Assembly & repair

  • modular system made up of few individual parts
  • assembly friendly
  • thanks to connection dimensions and performance data according to DIN EN ISO 2858, previous pumps can be easily replaced


  • DIN EN ISO 2858, 5199


  • EC Machinery Directive
  • EC Atex Directive

*In general, media with solids content can be transported, but application-specific verification in advance is absolutely necessary.
