Application: Irrigation/Automatic water sprinkler system Garden Fountains Livestock/Living water supply Water treatment systems Large Scale Watering System for Commercial Feature: Free run. Save money, environmental protection is the advantage of our solar submersible pump for irrigation . The controller also protects the pump from frequent start up in low light conditions, overheating & running dry. Batteries can also be connected via the controller if you need the flexibility of pumping on demand at any time. Low water level sensors & tank full sensors are included so the pumping system can be fully automated. With sensors installed, the pump will switch off if the header tank is full or if the water source has fallen below the pump intake. Automatic restart when water returns to the well or when the motor temperature returns to the safety range. Easy installation, maintenance-free, safe and reliable. Compact structure, high-lift, noiseless, non-pollution, complete electrical protecting controller device.
