Wrong fountain pump A wrong pump is one which is too small for the task. Similar to wrong nozzle it is possible to have a pump which is too small to operate the nozzles.
As you can see, it works fine. That is if you want only 4 jets each 1 m high. But suppose you want more jets say ten or twenty you are going to require a bigger pump if you want either more jets or jets higher than 1 m.
In short, the more nozzles / jets you have for a given pump, or the wider the jet outlet is the lower the final result will be. We were asked why would some one want that many single jets? The answer is sometimes people will "acquire" an old spray ring, they connect their "pond pump" to it and get really low jets because the pump is just not powerful enough. Most spray rings require two or more pumps to keep up with the water demand of all the nozzles. It is also a similar case if you have a pump with a high pressure but low flow rate, these type of pumps are often used to pump water from deep wells, they need the high pressure to get the water up from the bottom of the well but they do not pump a large quantity of water since in most cases they fill a storage tank for later use. In short, the more jets or the wider the jets are the less height you will get from the same pump. You can always turn as big pump down, you can not turn a small pump up. Nozzles, pumps etc are available from the components website Related links:
