Sunpal Submersible Solar Water pump
Sunpal solar submersible pumps are fitted with a permanent magnet, brushless motor, which enables the efficient use of energy from a wide range of supply options. The external controllers provide users with a variety of options,while offering the MPPT function-Maximum Power Point Tracking, maximizing the utilization of power generated from the photovoltaic generator.
Solar Water Pump Raw Material
-
Made of 100% stainless steel AISI 304
-
Double outer and inner shielding structure
-
Internal coil made from high-temperature tolerant, cooper wire,efficiently protecting the motor under high-temperature environment, extending motor’s service lifetime.
-
Water-filling lubricated rotor with top and bottom graphite-made bearing and thrust bearing made with high precision
-
Co-axial rotation efficiently reduces motor’s vibration and noise and extend its service lifetime
-
Built-in, integrated Variable Frequency Converter with intelligent-speed control algorithm with a maximum speed 6000RPM
Dry-run Protection
This function refers to the pump pumps out water on well, the system can automatically detect the anhydrous state,pump will stop working automatically by set program.Dry-run protection is effective all working modes,in manual mode, float switch model and solar mode.Pump will Standby for 30 minutes torestart the work(meet the start condition).Start to detect again whether there is water or not,if no water,stop working automatically; there is water, keep working, that cycle repeats.
