1)The efficiency has been enhanced by 15%-20% 2)Save energy by making use of solar energy ●Output of brass or stainless steel connector/oil cylinder
●The whole 304 stainless steel rotor shaft avoids the risk of shaft breakage
●Japanese NSK bearing: Extend the operational lifespan of the pump
●Double bearing structure at the bottom of rotor, using angular contact bearing, can withstand greater axial pressure ●Silicon carbide-impregnated graphite mechanical seal: lmproved longevity and enhanced dependability ●180°C high temperature resistant copper wire, insulation class F ●The magnet is made of 40SH NdFeb, with a temperature resistance of 150°C ●DC Controller:
1) Waterproof grade: IP65 2) Ambient temperature: -15C to 60°C 3) MPPT function: the solar energy will play a bigger role
4) Wide open circuit voltage range 5) Visual display: LED displays the power, voltage, current, speed etc working condition and error code 6) Speed conversion fuction: As a solar power,the sun can be repeatedly changed by itself.The user is able to control the speed of the pump by hand 7) Automatic startup and shutdown, without personnel on duty 8) Soft start: No impulse current, protect the pump motor 9) Multidirectional protection: High voltage/Low voltage/Over-current/High temperature protection ●Extra long warranty: Other than warranties for other similiar products,the warranty of this product is up to 2 years Spare parts:
