Macro Submersible Pump

Features
  • Oil Filled Motor
  • The motor are designed for a wide voltage range of operation and are suitable for installation in areas experiencing wide voltage fluctuations.
  • Motors are designed using enameled copper wire instead of PVC insulated copper wire.
  • Due to this the design is highly efficient reducing power consumption & thereby reducing cost of operations.
  • The motors are filled with special food non-toxic dielectric oil, which lubricates the ball bearing and axial thrust bearings. It also offers insulation and thermal properties which increases the reliability & working life of the motor.
  • Outer casing of the motor is constructed completely with Stainless Steels, Which reduce corrosion and gives a good overall appearance to the motor. 
  • The motors are compact and weigh substantially less, which facilities transportation storage & installation.
  • The electric cable of the motor constitutes three-wire removable cable with waterproof connector. This facilitates the changing of the cable, if required, without dismantling capacitors.
  • All rotating components and assemblies are dynamically balanced to ensure long bearing life and vibrations free smooth operations.
  • The motor are permanently split capacitor motors, which do not require the starting capacitors. Due to this cost of the control box reduce substantially, thereby reducing the cost of installations.
  • The pump sets are compact and slim and can be easily installed in narrow wells.
