4SP8-8  could offer adequate water for people ,livestock or irrigation rural site










Q&A

Q1  Is there anything different between your products and other factories
A1  Yes, we would like say there have some obvious different from our solar pump and other factory solar pump ,first all of my factory pump is BLDC pump ,we use rare earth for magnet in rotor ,it is new technology in pump motor business ,we are the first company who could use this kind of technology in submersible pump industry  .so you will see all of rotor in my factory is magnet rotors .
The second all of our motor is water motor , we are the first one and the only one we owned water motor technology in pump industry also ,there have two kind of motor in pump business ,one is water motor,another one is oil motor ,you could found some top famous brand such as grundfos ,franklin ... all use water filled motor ,but some middle and low class level brand  use water filled motor , why all famous brand would like water filled motor ?because water motor efficiency higher,life longer ,low noise ,no need maintenance,no pollution risk.why all Chinese factory except Samking use oil filled motor? because they do not have water filled technology .
the third we different Samking from others is Bulit-in design ,we also is the first one and the only one who could make built-in controller factory ,because we would like have a stable signal between motor and controller
the fifth is we could offer the most variety solar pump options , we offer internal controller option,external controller option,SS impeller pump end ,plastic impeller pump end ,AC/DC hybrid water pump ,DC water pump, 1.25inch ,1.5inch,2inch,2.5inch,3inch,4inch ,5inch,6inch,8inch,0.3hp ,0.5hp,1hp,1.5hp,2hp,2.5hp,3hp,5hp,10hp,20hp,
