Hopper feed pump Type KL-R Triplex

Pumps of the KL-R Triplex series impress with their consistent dosing option, as an intermittent input is compensated by the buffer volume in the collecting container. The small space requirement and large receiving vessel are a result of the low construction and the large volume of the container. No bridge building of the media possible.
Max. flow rate (gpm)
Max. differential pressure (bar)

Benefits and Characteristics

  • buffer volume up to 2.642 gal possible
  • modular design for high flexibility and short downtimes for maintenance and repairs
  • constant metering because the discontinuous input is compensated by buffer volume in the collecting container
  • unattended operation possible
  • excellent metering, important for dryer and incinerator operation
  • easy to maintain thanks to large cleaning openings
  • low-pulsation, continuous conveyance independent of pressure and viscosity
  • optimum service life even with difficult media
  • high operational reliability
  • high pressure performance
  • high dosing accuracy, also at low speed
  • low Life Cycle Costs
  • low construction with large container volume
  • little space required, with large collecting container
