Vertical motors can be identified by their capacity for an external thrust load. One common application with this factor is vertical pumps. The thrust load applied is the sum of the weight of the pump line shaft, the column of water in the casing that is being lifted, the weight of the pump impeller and the thrust produced by the pump’s volutes which forces the water to move upward.  The distance between the motor and the impeller can be very short such as pumping from a tank at or above ground level to lifting water from a subsurface aquifer several hundred feet deep. In the lat­ter example, the combined weight of the thrust load can be thousands of pounds (kilograms). The motor must then have a bearing design capable of these loads utilizing thrust bearings.
