6” Water Lubricated Cast Iron Motors (50/60 Hz)

Unnati UW6 series 6” Cast-Iron Submersible Motor is perfect for water-wells of 6-inches or larger diameter. The motor is pre-filled with a mixture of anti-corrosion fluid and clean water,it is fitted with radial and thrust bearings. Its dynamically balanced rotor ensures longevity of the motor and efficient performance through uniform clearance. It is Fitted with shaft seals, ‘O’ rings and sand guards to prevent leakage of lubricant or ingress of well-water or pollutants. It has high-end thrust bearings that can withstand extreme axial thrust loads and with pressure-equalizing rubber diaphragm that protects from fluctuating pressure and volume, 6 inch Water Lubricated Cast Iron Motors are useful for pressure-boosting units, mining industry, industrial water supply, irrigation, oil-and-gas industries, firefighting, de-watering, residential purposes, fountains, drip/sprinkler systems, and gardening/horticulture. It’s mounting dimension follows ‘NEMA’ standards.
