Dear Sir: In my opinion, there is no mandatory to use two pumps. MOst insurance companies recommend to use one diesel driven pump to achieve water demand. If you have the money, you can install two pumps but both must be rated at the sprinklers maximun demand. I have seen some problems using two pumps for sharing the whole water demand because if you lose one you will be in troubles. Remember that your design is for suplying all the water in the worst scenario. If you split the pump rating and if you lose one pump, this worst scenario could not be covered by one half-demand-rated single pump .
