Heidra 150MR
The Godwin 6" (150mm) Heidra 150MR hydraulic submersible pump offers improved performance and operating efficiencies that cannot be matched by standard electrical submersible models. With variable speed diesel engine power, the Heidra 150MR can meet a variety of flow and head requirements up to 1900 gpm (120 l/sec.) and 160 feet (48.8M) of total dynamic head with a simple throttle adjustment. Add the ability to pass solids to 3" (75mm) in diameter, dry running capabilities, a cast chromium steel impeller, and you have a rugged dewatering/solids-handling, self-contained 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, so pump loads do not affect gear motor performance.
- Double mechanical seal in its own clean oil bath allowing for indefinite dry running. Outboard seal: silicone carbide. Inboard seal: carbon or ceramic.
- Standard impeller is designed for general pumping, slurries and sludges. Available vortex impeller provides greater solids-handling capabilities.
- 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.
