Submersible Dredging/Slurries/Solids

Global Pump Dragflow heavy duty submersible agitator pumps are designed for handling slurries with a high content of abrasive solids. The pumps have been extremely successful for clients operating in specialized sectors who face severe conditions and difficult applications including dredging in the marine and energy sectors as well as in mining for minerals and other materials. Handling slurries with up to 70% solids content and specific gravity up to 1.7, with a capacity of up to 5300 gpm at 275 feet of head.

  • Electric motors are all Class H insulated and have a minimum 1.25 service factor.
  • Pumps are equipped with a unique lip seal system to prevent material from penetrating the seal.
  • High quality materials ensure long life of all components.
  • Temperature sensor, embedded in the electric motor, and Moisture sensor, in the oil chamber, are available options to protect the pump in the most demanding application.
  • Adjustable Hi-Chrome suction side Wear Plate maintains maximum performance for extended periods by a simple adjustment of the gap between the wear plate and the impeller.
  • Replaceable wear parts: casings, impellers, wear plates all can be replaced independently.
  • Lube Oil Inspection Ports: a wideangle port outside the pump ensures easy inspection of shaft seal oil levels as well as providing easy access for oil replacement.
  • The excavating action is created by the Hi-Chrome agitator blades that lift settled sediments which then get sucked into the pump, creating a continuous flow of concentrated slurry.
