A submersible pump for well that is literally,submersed under water.Usually used in a scenario where water is not available above ground (like a river or stream),thus drilling a hole and installing the pump into an underground water source.Submersible water pumps are designed to be fully or partially submersed in the fluid they are pumping.Since the pump is submerged in water,there is no need for pipe flanges,tube inlets or other types of inlet connections.
