What Is an ANSI Pump?
The pump type defined by ASME B73.1: design features, typical uses, materials and how it differs from ISO and API process pumps.
Read what an ANSI pump isANSI/ASME B73.1 Explained
What the standard fixes, what it leaves open and how dimension designations group pump sizes.
Open the B73.1 guideHow to Read ANSI Pump Size Codes
Nozzle order, impeller size, group prefix and suffix letters, with a Goulds 3196 pattern to Durco Mark 3 pattern conversion table by designation.
Read the size code guideANSI, ISO and API Pump Standards Compared
ASME B73.1, B73.2 and B73.3, ISO 2858, ISO 5199 and API 610: which fix dimensions and what that means for a replacement.
