Salient Features
- Oil-bath lubrication — superior heat dissipation, low winding temperature
- Suitable for any installation orientation (vertical / horizontal / inclined)
- Higher restart frequency capability than water-filled equivalents
- Dual-coat enamelled copper winding for slim profile and high efficiency
- Hermetically sealed — oil contained by mechanical seal + epoxy paint
- Stainless steel motor shaft (SS 420) and SS 304 motor shell — corrosion resistant
- Cast iron upper / lower brackets with epoxy paint
- Single-phase variants: capacitor start and run
- Three-phase variants: DOL up to 5 HP, star-delta above
- Class B insulation, IP58 protection
- IS:9283 / IEC 60034 standards compliant
- Wide voltage tolerance (+6% / -10%)
- Designed for 30 starts/hour service
- Coolant: die-electric non-toxic oil — safe for drinking water borehole environments
Applications
- V3 / V4 borewell submersible pump sets
- Horizontal & inclined installation duty (lakes, ponds, tanks)
- Solar submersible pumping (small / medium farms)
- Locations with frequent starts (≤30/hour)
- Domestic & low-head agricultural pumping
- OEM pump-set assembly
- Project installations & EPC supply
Use only the supplied die-electric non-toxic oil. Check oil level before installation and after major service.
For drinking water duty, food-grade white mineral oil is mandatory — confirm with our technical team before ordering.
Motors with other voltage and frequency ratings (e.g. 110 V / 60 Hz single phase) are available on specific demand.
