Engineered for deep-well duty
Every Majestic submersible motor is wound with enameled copper wire, runs on anti-friction ball bearings and is sealed for permanent submersion (IP 68 oil-filled / IP 58 water-filled). A high-strength stainless-steel shaft and NEMA-standard coupling let each motor pair directly with our submersible pumps for a complete, ready-to-run set.
- Sealed for continuous submersion (IP 68 / IP 58)
- Class F insulation & S1 continuous duty
- Stainless-steel shaft, NEMA-standard coupling

FAQ
What is a submersible motor?
A sealed electric motor built to run fully submerged inside a borewell, directly coupled to a submersible pump to lift water from deep underground.
Oil-filled or water-filled — which should I choose?
Oil-filled motors use a non-toxic dielectric oil that cools and lubricates the windings and bearings for smooth, long-life running. Water-filled motors use clean water and suit installations where oil contact with the water must be avoided. Tell us your application and we'll advise.
Can the motor be matched to a Majestic pump?
Yes — our motors are sized and rated to pair directly with our submersible pumps, so you can order a complete, ready-to-run pump-and-motor set.
Do you supply in bulk for projects?
Yes — we support bulk and export packaging for projects of any size, with export-ready documentation. Contact sales for project pricing.
