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.

The first seal separates the pumped fluid from the sealing liquid, the second one acts as a hermetic seal between the sealing liquid and atmosphere. If one of the two seals leaks, the second one ensures that the material being conveyed does not leak. This design optimised by CP with its own Futuramik® double mechanical seal offers decisive benefits to industries that pump hazardous and corrosive fluids with a high percentage of abrasive solids. This ceramic lined pump with a double mechanical seal on the top shaft stands for ultimate safety.


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 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

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