Why not just sequence them to start via the pump controller settings?

Would fire pumps with Pressure Limiting Devices be the best choice? Each pump will be 2500 GPM @ 125 PSI. My original design was based on pressure drop in the mains at 10 second intervals for each pump to start. The jockey pump is nominally designed to maintain 170 PSI and this is an FM job. So my question is: Are PLD's the best way to select fire pumps/drivers when you have multiple pumps or is it best to select traditional type drivers? Thanks.
