hopper feed pump Type KL-RUE

Pumps of the KL-RÜ series are built according to our proven modular principle. This allows high
flexibility, low spare parts inventory, and minimum downtimes for repairs. Other features include: sophisticated and robust cardan joints with screw conveyors, fibers do not get wrapped around the joint and the joint connectors thanks to the effective
protection device.

Benefits and Characteristics

  • maintenance-friendly
  • robust bearing pedestal with close-coupled drive and self-centering of the drive shaft (optionally with bare shaft)
  • various hopper sizes available
  • low-pulsation, continuous conveyance independent of pressure and viscosity
  • gentle pumping
  • modular design for high flexibility and short downtimes for maintenance and repairs
  • almost pulsation-free conveyance
  • modular design for short downtimes
  • consistent modular principle for high flexibility, low stocking of spare parts, short downtimes for maintenance and repairs
  • compact construction based on modular principle for high flexibility
  • no tangling of fibers around the joint or joint connections
  • long service life
  • high pressure performance
  • high dosing accuracy, also at low speed
  • high operational reliability
  • good price/performance ratio (standard product group)
  • good pumping performance even with abrasive and fibrous materials in the media
  • large viscosity range
  • constant metering because the discontinuous input is compensated by buffer volume in the collecting container
  • low Life Cycle Costs
  • unattended operation possible
  • excellent metering, important for dryer and incinerator operation
