3” Water Lubricated Motors (50/60 Hz)
Unnati UW3 series submersible motors are perfect for water-wells of 3-inches or larger diameter as it maintains uniform clearance for improved efficiency and longevity. The pre-filled motor comes with a mixture of clean water and anti-corrosion fluid. Fitted with polypropylene copper wires for stator winding and shaft seals, ‘O’ rings and sand guards prevent lubricant leakage or ingress of well-water and pollutants. Additionally, the pump is fitted with radial and thrust bearings (water-lubricated) that resist the elevated axial thrust loads. The pressure-equalizing rubber diaphragms protect against the varying volumes and pressure. Hence, 3-inch water-lubricated motors are useful for residential use, fountains, gardening/horticulture, and pressure-boosting units.
