6” Water Lubricated Stainless Steel Motors (50/60 Hz)

Unnati UW6 series 6” stainless-steel submersible motor is perfect for water-wells of 6-inch or larger diameter. It has a motor pre-filled with a mixture of anti-corrosion fluid and clean water. Its shaft extension and stator shell are made from stainless steel. Fitted with water-lubricated radial and thrust bearings, its pressure-compensation diaphragm protects the motor from fluctuating pressures and volume that could lead to damage, otherwise. On request, mechanical seals can be added. 6 inch Water Lubricated Stainless Steel Motors can be used 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.
