Why can’t the head of self-priming pumps reach a higher value?/

Why does the head of a self-priming pump be relatively low?
Is there such a saying too? I’m too ignorant
Yes, the head of self-priming pumps I’ve seen isn’t very high; it’s generally below a few dozen meters. These pumps are designed for specific purposes and require self-priming capabilities, which means that other parameters and functions are inevitably compromised
The reason why the head of a self-priming pump is not high is related to its internal structure. The internal losses are relatively high. If a high head is required, the vacuum water lift tank combined with a pipeline pump system can be considered.
Self-priming pumps have relatively low efficiency; a booster pump can be used when a high head is required
Won’t a high-self-priming pump solve it? This issue doesn’t seem like an issue at all!
The application of a self-priming pump determines its design parameters. It is possible to achieve a very high output head if required.
