Our solar water pump systems feature permanent magnet DC brushless synchronous motors that increase efficiency by 15%-20% while saving energy consumption. The rotor shaft is constructed from 304 stainless steel to prevent the risk of breakage. Additionally, our pumps are equipped with brass or stainless steel outlet/connectors/oil cylinders for superior corrosion resistance. The double bearing structure at the bottom of the rotor, along with angular contact bearings, ensures the pump can withstand greater axial pressure. Furthermore, our pumps are designed with 180℃ high-temperature resistant copper wire and 40SH aluminum iron boron magnets that can withstand temperatures up to 150℃.
