4” Oil Lubricated Stainless-Steel Motors (50/60 Hz)
Unnati UO4 series submersible motors are ideal for water-wells of 4-inches or larger diameter. Fitted with premium ball-bearing it ensures consistent performance and durability. For robust stator winding it’s fitted with enamelled copper (class H) wire. The high-end carbon/ceramic mechanical shaft seal or oil-seal made of Nitrile rubber to ensure flawless sealing. To protect motor against fluctuating pressure and volume, the motor is fitted with pressure-equalizing rubber diaphragm. Shaft seals, ‘O’ rings and sand guards prevent the ingress of pollutants and well-water and leakage of lubricant. The operating cost of 4 inch Oil Lubricated Stainless Steel Motors is low due to high-efficiency electrical design and it’s useful for irrigation, pressure-boosting units, industrial water supply, fountains, drip/sprinkler systems, and gardening/horticulture.
