If these are electric pumps, power to the pumps must be sufficient such that
both can operate as anticipated.
Also, NFPA 20 has required the following for fire pump field acceptance flow
testing since 2010:
Where simultaneous operation of multiple pumps is possible or
required as part of a system design, the acceptance test shall
include a flow test of all pumps operating simultaneously.
Hope this helps,

NFPA 25 added a section regarding this in 2023.
8.3.3.11: Where simultaneous operation of multiple pumps is required to meet
the water-based system demand for flow and pressure, the requirements of
8.3.3.10(2) shall be repeated at each flow condition with all pumps operating
simultaneously.
So, your test-header will need to accommodate the combined flow.
Hope this helps!

I would think you would need to do both, at least initially. Individually to
find out that each pump is working correctly itself and both to verify that the
full demand can be met.
For a future testing program, probably something specialized would be needed.
Make sure it is available in writing.

I have a project that requires two 1500 gpm pumps to meet the most demanding
system requirements. Client doesn't want any pumps over 1500 gpm. Long story.
As far as testing, would you test each pump individually or together or ??
Trying to establish what we need as far as a test header.
Thanks.
