Sprinkler Pump Pressure
What dictates the pressure a sprinkler pump will deliver? I have looked
at several. Many show GPM for 30PSI. However, they don't specify what controls the 30PSI. Is that the max PSI? They don't say. In reading about centrifugal pups this is what I think happens. 1. Pump attepts to reach max flow. If no resistance, then pump will deliver its max rate with very little PSI. 2. If there is resistance, then pumps flow will reduce based on the PSI. My sprinkler heads are rated for a GPM at a specific PSI. But the pump does not try to deliver a PSI it tries to deliver a GPM. And the PSI only goes up when the GPM can't be achieved. So I should be good so long as my sprinkler pump is rated for more GPM than my heads. Which is odd because from 1/2 HP up to 2 1/2HP the GPM is very much the same. The stronger pumps are not delivering that much more. Why buy a strong HP sprinkler pump? Carl |
