Hygienic progressing cavity pump Type KL-SL Hygienic

The pumps of the KL-SL serie convince through their easy cleaning and minimal deadspace construction. They can run heat- or coolable. Hygienic highlights are for example CIP (Cleaning in Place) as well as low pulsation and continuous conveying, independent of pressure and viscosity.
Max. flow rate (m³/h)
Max. differential pressure (bar)

Benefits and Characteristics

  • maintenance-friendly
  • optionally with one or two tangentially inclined cleaning connections
  • can run dry
  • top results for SIP and CIP cleaning
  • robust bearing pedestal with close-coupled drive and self-centering of the drive shaft (optionally with bare shaft)
  • low-pulsation, continuous conveyance independent of pressure and viscosity
  • gentle pumping
  • optionally with base plate or mobile
  • optionally with heating or cooling jackets
  • low servicing costs
