This is a quality made mini submersible water pump. It can be inlined or submersed for water pumping. It's built by a brushless motor to provide a smoother and quieter operation than a brush water pump. Also, it will not generate an 'electric spark' like what a brush type does, so it's safer. It can be used to pump oil as well (no gasoline*).
