Please suggest HDPE pipe size determination for borewell in Indore, Madhya Pradesh

We recently (mid of July) digged 6" borewell up to 455 ft in Indore location. Casing installed is 22 ft. According to the Boring Agent water stuck is 2". We are planning to install 2 HP pump. Can any one please suggest correct pipe size should be chosen for proper yield even during summer season. Some pump dealer suggesting 1" pipe and some are suggesting 1.25" pipe. We have to pump water till 3 rd floor.
