EB – PFA-Lined Double Mechanical Seal Chemical Process Pump

Discover the benefits of the EB produced by CP here – The centrifugal pump lined with PFA is ideal for corrosive 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 Futuratef®double mechanical seal offers decisive benefits to industries that pump hazardous and corrosive fluids with a high percentage of solids. Like the magnetic drive MKPL, the PFA coating is of the highest quality and therefore ideal for corrosive media even under vacuum conditions or high temperatures. This PFA-lined Pump with double mechanical seal on the top shaft ensures maximum safety.


Special features

  • Metal reinforcement with thick, vacuum-tight, corrosion and diffusion-resistant PFA lining.
  • Achieves low NPSH values.


  • Double mechanical seal
  • FuturaTef®: 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 16
  • Dirt-resistant, open plastic impeller with metal core
  • Clearance of the impeller can be optimally adjusted from outside
  • Bearing frame lubricated with oil
  • Single-stage centrifugal pump

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
