MKP Bio – Stainless Steel Magnetic Drive Biotech Process Pump

Discover the benefits of the MKP Bio produced by CP here – the CIP pump for sterile processes in the pharmaceutical and biotech industry.

Because the MKP-Bio has no shaft seal, micro-organisms are prevented from penetrating the pump. The torque is transmitted via a magnetic coupling, which is designed according to the inverted drive principle. Thanks to its special design, the MKP-Bio does not need a plain bearing carrier. The one-part, centrally arranged impeller bearing system is optimally flushed and cooled by the pumped fluid. The pump thereby achieves outstanding running properties. The impeller rotates steadily around a stationary axle according to the gyroscope principle and is hydraulically optimally balanced. Only slight bearing forces act on it, which increases its operating safety.


Special features

  • 100 % drainable (no flushing, drain or ventilation connections
  • 100 % cleanable (CIP)
  • 100 % sterilisable (SIP)
  • Self-venting
  • Parts in contact with medium: Surface quality Ra ≤ 0.8, inside edges R3, surfaces inclined > 3°


  • Compact & free of dead space
  • No shaft feedthrough & leak-free
  • Single-part & central bearing
  • Vertical installationno shaft seal (=no penetration by micro-organisms)
  • No plain bearing carrier
  • Single-part, centrally arranged impeller bearing with optimal cooling and flushing (=optimal running properties)
  • Low bearing forces due to hydraulically balanced impeller
  • High material flexibility
  • Inverted drive principle
  • Single-stage centrifugal pump

Assembly & repair

  • Modular system made up of few individual parts
  • Assembly friendly
