AB - We present the results of searches for nucleon decays via p → νπ<sup>þ</sup> and n → νπ<sup>0</sup> using a 0.484 Mt · yr exposure of Super-Kamiokande I-V data covering the entire pure water phase of the experiment. Various improvements on the previous 2014 nucleon decay search [Phys. Rev. Lett. 113, 121802 (2014)], which used an exposure of 0.173 Mt · yr, are incorporated. The physics models related to pion production and nuclear interaction are refined with external data, and a more comprehensive set of systematic uncertainties, now including those associated with the atmospheric neutrino flux and pion production channels, is considered. Also, the fiducial volume has been expanded by 21%. No significant indication of a nucleon decay signal is found beyond the expected background. Lower bounds on the nucleon partial lifetimes are determined to be 3.5 × 10<sup>32</sup> yr for p → νπ<sup>þ</sup> and 1.4 × 10<sup>33</sup> yr for n → νπ<sup>0</sup> at 90% confidence level.
