Advantages of Water-filled Motor Solar Pump
- Double inner and outer shielded deep well pump with field-oriented control function, is made of 304 stainless steel. More environmental protection, no oil pollution.
- The whole 304 stainless steel rotor shaft with ceramic plating process at both ends, is more wear-resistant.
- Water cooling structure of shielded motor, without mechanical seal, solves the problem of water leakage of traditional water pump motor.
- Shielded motor adopts graphite bearing, which has strong self lubrication and corrosion resistance, and can operate reliably in the form of water lubrication.
- Thrust bearing, providing strong and stable thrust.
- Submerging depth can reach 150 meters.
- Over-voltage/undervoltage/over-current/phase loss/short circuit/water shortage/high temperature protection etc.
- 3 years warranty.
