Encapsulated Motor

• Deehp Encapsulated Submersible Motors adopt integrated full resin encapsulation design. High-insulation resin fully wraps stator windings to achieve reliable waterproofing and powerful anti-sand performance.

  ✅ Full resin sealed winding structure

  ✅ F-class insulation & efficient underwater cooling

  ✅ Precision balanced rotor for low vibration running

  ✅ Multi-layer sealing to prevent water penetration

  These motors maintain stable efficiency during long continuous operation, perfectly matching deep well pumps for residential water supply, agricultural irrigation and industrial water extraction.

• Reliable Components & Design Advantages

  

  Slinger (Sand guard)

  The slinger (sand guard) prevents sand in well water from entering the mechanical seal and penetrating into the motor interior.

  

  Heavy thrust capacity

  Heavy-duty bearings support bidirectional rotation and withstand high thrust loads.

  

  Adjustment screw

  The standard shaft height can be precisely adjusted via the adjustment screw on the thrust bearing base.

  

  Graphite bearing

  The graphite bearing features internal channels for easy water lubrication, and accurately guides the rotor shaft during up-and-down movement.

  

  High quality mechanical sealing system

  High sand resistance with IP68 protection class. While many manufacturers treat the mechanical seal as an optional part, Deehp equips it as standard to block sand and particles from entering the motor and extend bearing service life.

  

  Core component: Rotor

  High-performance core component to boost efficiency, save energy and reduce environmental impact.
