Different manufacturers produce different versions of it; this is probably used for positioning. The principle of these pumps is that of positive displacement pumps, which are equivalent to gear pumps. If a large pressure difference occurs, it is necessary to check whether there is any blockage in the circulation system, such as filters (screens) before/after the pump, or detached valve components, and so on. For reference.
