How much power does the 3/4 hp motor draw at 115 V and 230 V?

The motor is rated at 13.0 A on 115 V and 6.5 A on 230 V, giving roughly 1.5 kW input either way.

What plumbing connections must already be in place for the 1-1/4 in NPT inlet and 3/4 in NPT discharge?

You need a 1-1/4 inch NPT suction line and a 3/4 inch NPT discharge line, plus a foot valve or check valve on the suction side.

Will the 25 ft maximum suction lift work with my existing 20 ft deep well point?

Yes, the pump’s 25 ft max suction lift covers a 20 ft well point, provided piping friction losses stay low.
