7” Water Lubricated Motors

Our 7” water-lubricated motors are pre-filled with an antifreeze agent that is used as a lubricant. These motors are fitted with three-phase power circuit. The rotors are designed to withstand maximum radial and axial thrust loads, as they are supported by durable thrust and bush bearings. We have followed NEMA standard when designing the mounting dimensions. You can easily rewind this motor. It can resist corrosion due to being made of stainless steel. You can easily dismantle and repair this motor. 7 inch Water Lubricated Motors are used for water-supply, agriculture, commercial buildings, industries, pressure-boosting units, livestock, watering, construction, firefighting, pivot-irrigation system, sprinkler, dewatering, and fountain.
