Heidra 103
The Godwin 4" (100mm) Heidra 103 hydraulic submersible pump is a compact, self-contained pumping unit featuring a diesel driven power pack and a 4" (100mm) submersible hydraulic top discharge pump. With variable speed diesel engine power, the Heidra 103 pump can meet a variety of flow and head requirements up to 1,000 GPM (227 m3/h), total dynamic heads to 170’ (52 m) and solids handling to 3" (75mm) in diameter.
- Unique top discharge design enables pump to fit through a 21" (533 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.
