Self-priming pump Type GL-S

The WANGEN progressing cavity pump of type GL-S is particularly well suited to umbilical hose systems. Large distances and height differences are mastered easily. It may be used as a stationary pump or mobile pump, attached to a slurry tanker or chassis. The comprehensive range of pumps available make them a product for universal use.

They carry watery or thick media, as well as media loaded with solids just as well.

Max. differential pressure (bar)

Benefits and Characteristics

  • low Life Cycle Costs
  • high operational reliability
  • high priming capacity
  • long service life
  • good pumping performance even against high pressure
  • consistent modular principle for high flexibility, low stocking of spare parts, short downtimes for maintenance and repairs
  • almost pulsation-free conveyance
  • easy fitting to slurry tankers or trolleys
  • smooth running thanks to hollow rotors
  • insensitive to foreign matter
  • easy to maintain thanks to large cleaning openings
  • high pressure performance
  • high suction lift (self-priming under certain conditions)
  • consistant diameters at joint connections for constant flow-rates
  • no foreign body deposits in the suction housing
  • no tangling of fibers around the joint or joint connections
  • consistent modular principle for high flexibility
  • optimum service life even with difficult media
