Jockey Pump Sizing

[GeorgeMech]

Other than the method of taking the 1% flow capacity of fire pump to calculate the jockey pump pressure capacity, is there any calculation method on how to size its pressure capacity. Also, what method should I used in order to size the flow capacity of the Jockey pump.thanks

I have a project (fuel storage for genset application,139 m2) that requires foam system, In this project I used the deluge system, foam-Bladder type, air aspirating system, design is 6.5 li/min/m2. but after submitting the design the consultant commented that the density should be 10.2 li./m/m2 based on the hazard occupancy and I should also calculate the foam leakage from doors,etc. So is it needed for us to calculate this foam leakage since that section is for the blower type and not for air aspirating and it the 6.5li/m/m2 is enough for this design.Thanks

There is no a simple answer, but there are several interesting old threads dealing on jockey pump sizing. You may type jockey pump on the "search" and it will give a list to read a little.
