Flush height refers to the maximum water flow height that can be achieved under a given pump water condition.
In other words, when the inlet and outlet of the pump are at the same level, if the outlet height continues to be raised until the outflow of water stops, then this height is the impact height. This value is an important parameter to measure the performance of the pump.

The impact of gravity and atmospheric pressure is the main reason for the impact of thrust elevation. On the one hand, due to the action of gravity, the water will naturally flow downward, without the action of external forces, the water cannot rise. On the other hand, atmospheric pressure can also have an effect on water flow. When the water reaches a certain height, the pressure at the bottom of the water column exceeds the atmospheric pressure, making it impossible for the water to continue rising. These two factors together determine the size of the thrust elevation. Blanking elevation is an important reference index for pump design and selection, which has an important influence on the safe and stable operation of liquid conveying system.
Washout elevation refers to the vertical height at a point in the flow. It is commonly used to measure changes in water levels in rivers, lakes or oceans. The thrust elevation is defined relative to a known datum, such as sea level or a fixed ground point. By measuring the difference between the water level and the datum level, the washout height can be determined. This is important for fields such as hydrology, water resource management and engineering design because it helps us understand how water bodies flow and change.
elevation refers to the distance from a point along the vertical line to the absolute base surface, called absolute elevation, referred to as elevation. The distance from a point along the vertical line to a presumed level base is called the assumed elevation.
