How high can a diaphragm pump lift water?

The maximum height that a mini diaphragm pump can lift water depends on a variety of factors, such as the design of the pump, the size and strength of the diaphragm, the viscosity of the fluid being pumped, and the atmospheric pressure at the pumping location. 

In general,  most mini pumps can lift water to a height of approximately 20-30 feet (6-9 m). Beyond this height, pump performance may begin to decline due to increased water column resistance and the weight of the fluid being pumped. In addition, some diaphragm pumps may have a maximum suction head specification, which is the maximum height at which the pump can absorb water, exceeding this limit may cause the pump to lose its volume and become inoperable. 

This will ensure that the dc pump chosen is capable of meeting the specific needs of the application and will perform optimally. Some important factors to consider when selecting a diaphragm pump include the flow rate, pressure requirements, viscosity of the fluid being pumped, temperature limitations, and any special features or materials needed for compatibility with the fluid or environment. Additionally, it is important to consider the reliability, durability, and maintenance requirements of the pump, as well as any safety considerations. By carefully evaluating these factors, the right micro diaphragm pump can be chosen to ensure efficient and effective pumping in the desired application.
