Parallel Pump System Manifold Design Help
(OP)
I am designing a pump station for a culinary water distribution system. I have two pump skids. The first is a 45 gpm pump (demands & pressure) and the second is a 1500 gpm pump (fire flows).
I am looking for any guidance or rules of thumb for sizing a suction and discharge manifold to connect these pumps in parallel.

You might want to place the fire pump first and the domestic pump downstream of the fire pump since it will be running 99 percent of the time it will keep the water in the header pipe fresh.
What about redundancy of the domestic pump?

I do have a redundant domestic pump on the skid, I just didn't mention it.

Suction piping is generally 4-6 feet per second and discharge piping is generally 6-8 feet per second. Minimize the length of the suction piping. Use an eccentric reducer on the suction side.
