Heidra 100

The Godwin 4" (100mm) Heidra 100 hydraulic submersible pump is a compact self-contained pumping unit featuring a diesel driven power pack and 4" (100mm) submersible hydraulic pump. With variable speed diesel engine power, the Heidra 100 can meet a variety of flow and head requirements up to 800 gpm (408.6 M3/hr.) and 120 feet (36.6M) of total dynamic head with a simple throttle adjustment. Add the ability to pass solids to 2" (50mm) diameters, 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.
  • Bearings are independent from the hydraulic gear motor – pump loads in no way affect gear motor performance.
  • Double mechanical seal in its own clean oil bath allowing for indefinite dry running. Inboard seal: silicone carbide. Outboard seal: carbon or ceramic.
  • Standard impeller designed for general pumping, slurries and sludges. Semi-recessed impeller provides greater solids-handling capabilities.
  • Standard two-bolt SAE flange gear motor connections.
  • Simple to maintain, gear motor with “plug-in” connection allows for quick changeover when required.
