8 Inch Water Lubricated C.I Klassic Motor (50/60 Hz)

Unnati UW8 series 8” water-lubricated C.I klassic motor is perfect for water wells of 8-inches or larger diameter. The motor’s connecting pieces, base and upper/lower housing is made of graded cast iron with epoxy paint while the stator shell and shaft extension are made from stainless- steel that offers durability to the equipment. Dynamically balanced rotor ensures uniform clearance, longevity, and efficient performance. The uniquely designed thrust bearings can withstand high axial thrust loads. While the pressure-compensation diaphragm protects the motor from fluctuating volume and pressure that could lead to damage otherwise. Fitted with shaft seals, ‘O’ rings and sand-guards to prevent the ingress of water or pollutants and lubricant leaks. 8 inch Water Lubricated C.I. Klassic Motors’ mounting dimension follows ‘NEMA’ standards. It’s useful for residential purposes, mining industry, pressure-boosting units, industrial water supply, irrigation, oil-and-gas industries, firefighting, de-watering, residential purposes, fountains, drip/sprinkler systems, and gardening/horticulture.
