HS80 Hydraulic Sub Pump

The Godwin 3" (75mm) Heidra 80 hydraulic submersible pump is a compact self-contained pumping unit featuring a diesel driven power pack and 3" (75mm) submersible hydraulic pump. With variable speed diesel engine power, the Heidra 80 can meet a variety of flow and head requirements up to 420 gpm (26.5 l/sec.) and 125' (38.1 meters) of total dynamic head with a simple throttle adjustment. Add the ability to pass solids to 1-9/16" (40mm) in diameter, dry running capabilities, a cast chromium steel impeller, and you have a rugged dewatering / solids-handling, hydraulic submersible pump ready to go anywhere.

  • Rugged construction featuring cast iron pumping chamber and cast chromium steel impeller.
  • The pump has independent bearings from the hydraulic gear motor, therefore pump loads in no way affect the gear motor performance.
  • Mechanical seal in its own clean oil bath allows for indefinite dry running. Seal faces are solid silicone carbide.
  • Standard impeller is designed for general pumping, slurries and sludges.
  • Gear motor connections are standard two-bolt SAE flange.
  • For ease of maintenance, the gear motor has a “plug-in” connection to allow for quick changeover when required.
