If the pool pump is hardwired, then this rule applies:
210.23(A)(2) Utilization Equipment Fastened in Place. The total rating of utilization equipment fastened in place, other than luminaires (lighting fixtures), shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.
So if you want receptacles on a hard wired motor circuit, then it can only draw half of the circuit's rating (which isn't likely with most 120V pool pumps).
