This could be true but I think that reliability of such system would be on low level which couldn't be acceptable for a fire fighting system, i.e. there must be an accumulator fitted in the system, see link below...
Hm...if you are true about the set pressure, then the only way to keep the pressure in the piping system without running the jockey pump, is that the pipes deforms a little in order to store the pressure energy, i.e. the pipes acts as some kind of hydraulic accumulators...
Artisi,
1. I know that there is a non-return valve in the discharge side if the jockey. But, if we consider following statements:
a.Water is a non compressible fluid,
b.None hydraulic accumulator fitted in the piping system,
c. steel piping considered as a rigid body/non deformable
In that...
Greetings,
I am reffering to a typical fire fighting sprinkler piping system acc to NFPA 13 or NFPA 20.
For example, the permanent pressurization of the ff piping system is required in order to prevent the main fire pumps from unnecessary start. This may be done by adding a centrifugal type...
