Heidra 100TD

The Godwin 4" (100mm) Heidra 100TD hydraulic submersible pump is a compact self-contained pumping unit featuring a diesel driven power pack and 4" (100mm) submersible hydraulic top discharge pump. With variable speed diesel engine power, the Heidra 100TD pump can meet a variety of flow and head requirements up to 800 GPM (182 m3/h) and 130' (39.6 m) of total dynamic head with a simple throttle adjustment. Top discharge design enables the pump to be lowered into a 19.5" (495mm) diameter opening. Add the ability to pass solids to 2" (50mm) diameters, dry running capabilities and a cast chromium steel impeller, and you have a rugged dewatering/solids-handling, hydraulic submersible pump ready to go anywhere.

  • Unique top discharge design enables pump to fit through a 19.5" (495 mm) diameter opening.
  • 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 allows for indefinite dry running. Inboard seal: silicon carbide. Outboard seal: carbon or ceramic.
  • Standard impeller designed for general pumping, slurries and sludges.
  • Standard two-bolt SAE flange gear motor connections.
  • Simple-to-maintain, gear motor with “plug-in” connection allows for quick changeover when needed.
