I have been searching for an Allis Chalmer's pump curve catalog for a while now, but it is impossible to find on the web.

I'm mainly looking for a catalog with the discontinued pumps like the PS-Plus and 731+ pumps. Wondering if any one has a pdf of these they wouldn't mind sharing.

I have them on paper, if I have the chance, I'll scan them and upload the files.

Could never understand why the 731 was discontinued, a well designed and comprehensive range which in my opinion better than what was retained to cover this market segment.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

From what I understand, the 731 was discontinued because it was an ANSI pump, and with the merger of Goulds and AC, there was no need for two ANSI pumps, and the Goulds 3196 was the clear winner, based on population and market share.

I think the files are too big, or my connection is too slow, to upload them here, but here is a link to the PSPlus curves, I'll do the 731s shortly

Correction, that's both files.

Ya I agree that the 3196 is overall a better pump, but the 731+ did have some great advantage. The dynamic seal that is on the 731+ pump is great, better than the 3196. They even have a double dynamic seal, which isn't in the 3196 line to my knowledge.

Thanks alot for the curves Ten!
