Buyers do not need to treat it as an abstract catalogue term: it is the margin that helps liquid remain liquid as it enters the pump. If that margin becomes too small, vapour can form in low-pressure regions and collapse as pressure recovers, reducing performance and potentially damaging the pump.</p>
