Oil Cooled Motor

• Deehp Oil-Cooled Submersible Motors adopt internal oil circulation cooling technology. Sealed cooling oil continuously absorbs and dissipate operational heat, delivering reliable heat dissipation performance under unstable water level and shallow submerging conditions. Built with premium insulation system, robust multi-layer mechanical seal, precision dynamically balanced rotor and anti-corrosion stainless steel housing, the motors feature stable efficiency, low vibration and excellent adaptability. As cost-effective matched drive units for deep well pumps, they are widely applied in household water supply, small-scale agricultural irrigation and scattered underground water extraction projects.

  
  

  ✅ Internal circulating oil cooling, works reliably even at low submersion depth

  ✅ Cooling oil offers dual performance: heat dissipation & bearing lubrication

  ✅ Reinforced multi-layer mechanical sealing effectively prevents leakage

  ✅ Compact structure, easy maintenance and outstanding cost performance
