●Permanent magnet DC brushless synchronous motor:
1)The efficiency is improved by 15%-20%
2)Reduce the consumption of solar panels to save energy
●The whole 304 stainless steel rotor shaft avoids the risk of shaft breakage
●Two options: Brass or stainless steel outlet/connector/ oil cylinder for option so that you can make better choose
●Japanese NSK bearing makes longer working life
●Silicon carbide-impregnated graphite mechanical seal: Longer working life and high reliability
●Double bearing: Double bearing structure at the bottom of rotor can withstand greater axial pressure
●Intelligent water shortage and full water protection.
●Adopt 180°C high temperature resistant copper wire, the class of insulation levels up to Class F
●With solar energy,the innovative pump can live in remote areas where electricity is not available.
