Coverco Submersibe Motors 6 inch for deep water well

The filling liquid is a dielectric fluid, known as white oil, approved by the FDA and other international pharmacological institutes. The coupling dimensions and flange comply with the NEMA standard, as these submersible motors are specifically designed to operate coupled with submersible deep well pumps with the same coupling dimensions.

The mainly three-phase power supply ranges between 4.0 kW (5.5 HP) and 30 kW (40 HP). The submersible motors are mainly used in vertical installations.

However, these motors can be installed also horizontally prior confirmation from our technical department and global assessment of the required application.

Coverco motors can be installed in 6’’ wells with a maximum depth of 350 metres. The rewindable feature is ensured by a design that allows the motors to be disassembled and reassembled.

Coverco Submersibe Motors application

Coverco Submersibe Motors 6’’ electric motors ensure reliable operation in wells with diameters equal to or greater than 6’’. The axial and radial oil lubricated bearings allow for maintenance-free operation. The pressure compensation inside the motor is ensured by a special membrane

ADVANTAGES

  • Stator in oil
  • Cable material compliant with drinking water standards (KTW)
  • Sand protection and mechanical seal to allow for optimal operation even in the presence of sand in the well
  • Designed to ensure excellent efficiency and low operating costs
  • All motors are pre-filled with liquid and 100% tested
