De juiste uitdrukking voor 'head' bij pompen is opvoerhoogte - het is iets anders dan druk

Zie het volgende extract van https://hollandaptblog.com/2014/02/07/what-is-pump-head-how-...

So what is the difference between pressure and head then? While some pump manufacturers that use pressure (differential pressure, that is) to characterize their pumps, this is not the most “accurate” way to do so. Head is useful because it evaluates a pump’s capacity to do a job. Most pump applications involve moving fluid to a higher level. If you have to pump a liquid up 30 feet and your pump doesn’t have at least 30 feet of head, then there is no chance it will work. Your pump will need at least 30 ft. plus the friction loss to get the required flow at the discharge point.

Beter: grote opvoerhoogten
