Sunpal Submersible Solar Water pump  

Sunpal submersible water pump adopt stainless steel casing, shaft core, coupling, water entry base and pump body (or copper alloy water entry base, pump body) to avoid rust or corrosion, stainless steel impeller and stainless steel blower inlet casing. New "floating style" structure of impeller avoids axial pressure to motor. With combination of motor and controller, the max efficiency is over 90%, raises 20% than the traditional AC one.

Solar Water Pump Raw Material

• Permanent magnet DC brushless synchronous motor, efficiency improved by 15%-30%;
• 304 S/S pump shaft;
• Brass or stainless steel outlet/connector/ oil cylinder;
• Japanese NSK bearing with longer lifetime;
• Double bearing motor base: can work under more axial pressure ;
• Alloy mechanical seal: Longer working life and high reliability;
• Motor coil is made by automatic winding machine with centralized winding technology,motor efficiency is much improved

MPPT Pump Controller Advantages:

• Waterproof IP65
• Ambient temperature:-15degree-60 degree
• MPPT function
