250W-3000W Solar water Pump, Self-Priming Pump with Brushless DC Motor,pump water supply

1.We research & develop and produce the solar power Brushless DC pumps. We research & develop and produce the solar power BLDC pump's controller too.
2.Three phase  brushless  DC motor without Hall sensors, high reliability. Solar energy starts the BLDC intelligently.
Adopt stainless steel screw and rubber stator, permanent magnet brushless motor, with combination of motor and controller, the Max efficiency is over 85%, raise 25% than traditional AC pump.
3. Adopting Soft start-up system for motor controller. The motor starts up placidly and the current is far less than traditional hardware startup technology.
4. By detecting the solar power circuit, the controller can prevent the motor from starting up frequently when the solar power is weal, Thereby it can protect the pump motor and prolong the motor lifetime.
5. High technique products adopting MPPT and DSP chip technique. The MCU can detect the circuit automatically and can be displayed by LED.
6.The pump include Over-voltage protection / Under-voltage protection / Over-current protection / Over-load protection.
Works from solar modules with or without battery storage via a Pump Controller or Pumping Maximiser.
7. Through groundwater and tank water level detection, as well as the current and voltage detection, the system can work automatically. When the current is overload, the system can restar automatically.
8.Water Level detector / Sensors is used to connected to the controller and can be used to protect the pump from running dry as well as to automatically turn the pump off when a water tank is full.
9.Battery back up, runs perfectly on overcast day and in the night.
10.Smart modular design for simple and cost effective servicing and repair.
11. Adopt double plastic package for rotor and stator, motor insulation ≥300MΩ,the motor security was much improved.
12.100% copper wire, cold-rolled silicon steel sheet. Cast stainless steel components.
13. Natural rubber of Sealing and rubber stator.
