Reasons for the water pump drawing in little or no water

Thread Content

Some water sources are deep, while in others the area surrounding them is relatively flat; this leads to neglect of the allowable suction lift of the pump, resulting in less water being drawn in or no water being drawn at all. It should be understood that there is a limit to the degree of vacuum that can be created at the water intake of a pump; the suction height achievable in an absolute vacuum is approximately 10 meters of water column, and it is impossible for a pump to create an absolute vacuum. Moreover, an excessive vacuum level can easily cause the water inside the pump to vaporize, which is detrimental to the operation of the water pump. Therefore, pumps all have a maximum allowable suction lift, which is generally between 3 and 8.5 meters. When installing water pumps, it is crucial not to prioritize convenience and simplicity.
