The WANGEN progressing cavity pumps of the KB-S serie are, in contrast to the KL-S serie, equipped with a block housing. There, the drive is coupled directly to the pump housing, which is ideal for normal pump operation or for small conveyed volumes. The pump conveys viscous and abrasive mediums.

Max. flow rate (m3/h)
Max. differential pressure (bar)

Benefits and Characteristics

  • compact design
  • good price/performance ratio (standard product group)
  • high suction lift (self-priming under certain conditions)
  • consistent modular principle for high flexibility
  • constant flow speed in the suction housing prevents desposits or sedimentation
  • optionally with base plate or mobile

Fields of Application
