PUMPS ARRANGED IN LINE

Question asked by Peter Stroinski on May 11, 2017

Can you advise?There are designed two sprinkler pumps arranged in line (first fire pump takes suction directly from a water supply and second sequential pump takes suction under pump pressure from the preceding pump)

Is it required acc. to NFPA keep distance 10 suction pipe diameters between discharge flange of previous pump to the suction flange of subsequent pump? Can it be shorter distance? Sketch in attachment.

Regards

Piotr
