Since your pump is not supported ONLY by piping I would say that F.2 does not apply. However, look at the most recent interpetation in API 610 there may be some help there.
Question If a pump vendor supplies a pump with API 610 specification and higher nozzle allowable loads (two times or three times higher) than those per Table 4 (T4). Is it acceptable to use the vendor allowable loads in Clause F.1.2 to satisfy all the conditions in F.1.2 a) through F.1.2. c) in Equations F.1, F.2, F.3, F.4 and F.5 instead of the Table 4 values when an Annex F calculation is performed?
Answer Yes
So if the vendor has allowed greater then table 4 loads you can then apply the criteria in appendix F to the pump
