Dear Sir,

I would like to request for fire pump setting , for Jockey pump star t point and stop point. And rest fire pumps,

For example

Fire pump rated pressure is 14.9 bar and its churn pressure is 16.1 ,kindly explain Jockey pump start point and stop point and follows the fire pump start point.

shall we keep the start point of jockey pump @ 14.9 bar and rest followed by 10 PSI less.

or only we need to keep the jockey pump stop pressure @ churn pressure of the pump 16.1 show in above example

If we keep the jockey pump stop point @ churn pressure 16.1 and rest followed by 10 PSI less .in this case the working pressure of the fire pump will be higher than the rated pressure ,so its leads to unwanted running.

Please refer the below example
