Does a vertical centrifugal pump have a suction lift?

Vertical pipeline centrifugal pumps do have a suction lift ‌.

The suction lift refers to the vertical distance ‌ by which a water pump can draw water from a lower place to a higher place, and is usually measured in meters ‌.

For vertical pipeline centrifugal pumps, the suction lift range is generally around 5 to 8 meters ‌. 

This value is influenced by a variety of factors, including atmospheric pressure, liquid properties, pipeline resistance, and pump body structure, etc.  

In practical engineering applications, 5-6 meters is a more common and reliable value ‌.

It should be noted that the allowable suction vacuum height indicated on the product manual or nameplate of the water pump is a theoretical value measured under specific conditions. 

When actually installing, the water flow conditions after the suction pipe is matched need to be taken into consideration. 

If there is a higher demand for suction lift, it may be necessary to consider using other types of pumps such as self-priming pumps ‌.
