Because of the size of deep well/borehole pump is very small and also the depth of borehole pump installation is quite deep, it is impossible for the pump user to install the liquid probe or float switch in the deep well to detect the liquid level, dry run is fatal problem to deep well / borehole pump, we adopt unique technology to protect deep well/borehole pump against dry running without install any liquid sensor or float switch.
Surface pump dry run protection dry run is a serious and fatal failure for any pump, in the installation of pump and routine maintenance, we can protect the pump against dry running without any liquid sensor or floats switch, so it can save the pump user cost and decrease the installation and maintenance work.
Typical application scenarios:
-Agricultural irrigation/ pumping
-Pressure Booster Systems
-Waste water treatment
-Water Tanks/Wells
-Drainage System
-Cooling Towers
-Flood Control
-Fishing Boat
