Pentair Aurora Pump — ASME/ANSI B — Model ANSI Pumps are a type of single-stage end suction centrifugal pump. This type is designed to the ASME B standard, and each size of this type of pump has. (b) This Standard has been revised to include solid polymer pumps formerly covered under ASME B The design and construction features for metallic.

Standards b73.11 an extremely important part of the industrial and commercial landscape. By specifying standards-compliant products, buyers can be assured that the items they acquire will meet important performance and safety requirements, even if they come from companies that the buyers have never dealt with before.

Standards also guarantee an important degree of interoperability between products from different manufacturers. All of this contributes to competitive markets and economic efficiency. This article will focus on a comparison of two important sets of standards for industrial pumps: ISO a language-neutral title for the International Standards Organization traces its roots back to when delegates from 25 countries met in London to discuss the future of international standards that could bridge the many national and industry-specific standards.


There are now more than 19, international standards covering many aspects of technology and business. However, there has been a degree of convergence as the two standards bodies borrow from each other. With the rise of globalization, ISO standards are increasingly influential. This standard was developed to address the needs of the chemical industry for a robust family of single-stage end-suction centrifugal pumps.

The standard covers 27 pump sizes and specifies a number of key dimensions for each of these.

Dimensions include overall height and length of the bare pump, nozzle and shaft diameters, the size, 7b3.1 and spacing of mounting bolts, etc. The older ISO focussed on external dimensions and mounting details, while ISO also specifies a variety of performance requirements e.

In some aspects e. However, most manufacturers of ISO pumps have 60 Hz models available. While of course the easiest and most straight forward option for a North American company may be to pursue only ANSI standard products, doing so significantly limits your choices.


Many of the ISO certified products coming out of Europe, and Germany specifically, have impressive new energy efficient technologies that may not be available in their ANSI counterparts.

There is a reason that German designed products are known for their quality, efficiency, and long service lives. Energy savings from a European ISO product may just make it worth the effort.
