Even though ANSI chemical pumps they are mostly used in the chemical and petrochemical industries, they can also be found in paper stock, ethanol production, pharmaceutical, food anzi and several other process plants.

Our vision is to build a digital community through websites, eNewsletters, and social media channels that allows pump industry professionals to exchange ideas, news stories, product information, case studies, videos, event information and more. 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.

By definition, these nasi pumps are horizontal, end suction single stage, centerline discharge, centrifugal pumps comparable in size and dimensions regardless of pump manufacturer. Backflow Testing…Working in a field that Makes a Difference.

The older ISO focussed on external dimensions and mounting details, while ISO also specifies a variety of performance requirements e.

ANSI Process Pumps – Empowering Pumps and Equipment

This article for Water Online discusses the need for a consensus body for developing a groundwater pumping systems standard to include guidance on performance requirements for pumps used in water wells.

In some aspects e. It covers metallic and solid polymer pumps and is designed to facilitate installation and maintenance, as well as to enhance the safety and durability of ANSI B Although mostly used in the chemical industry, ANSI process pumps are also used in food processing, paper mills, pulp mills, refineries, ethanol production, textiles, and various other process plant applications.


This article will focus on a comparison of two important sets of standards for industrial pumps: Ansk definition, these centrifugal pumps are horizontal, end suction, single stage pumps that are comparable in size and identical in interface and envelope dimensions, regardless of manufacturer.

The main focus of this standard is that all ANSI pumps manufacturers offer interchangeable equipment with respect to mounting dimensions, size and location of suction, and discharge nozzles, input shafts, baseplates, and foundation bolt holes. 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.

ANSI pumps offer plant operators the possibility to switch pumps and brands without having to change or redesign motor attachment, piping, coupling or baseplate dimensions.

Saving energy efficiently December 27, Please enter your comment! The total head pressure ranges from 50 to feet 22 to psiand horsepower from 1. Go to subscribe form No, thank you. Monday, December 31, With the rise of globalization, ISO standards are increasingly influential. This ANSI process pump sizing standard is broken down into three main groups. These pumps also perform beyond standard metrics and offer a max flow capacity to 7, gpm, total head to feet, and can even accommodate fluid temperatures up to degrees F.

This website uses cookies to enhance your experience. 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.

Since then, the committee has continued to be active and has defined the standards for 27 pump sizes through several revisions.

ANSI Process Pumps

The standard covers 27 pump sizes and specifies a number of key dimensions for each of these. There is a reason that German designed products are known for their quality, efficiency, and long service lives. The plugin only becomes active when you click the button, which indicates that you agree to communicate 7b3.1 the social network.


Given the end suction and centrifugal design of ANSI process pumps, they are ideal for transferring water and mostly thin liquids.

Dimensions include overall height and length of the bare pump, nozzle and shaft diameters, the size, location and spacing of mounting bolts, etc. The purpose of the standard is to ensure that other ANSI process pumps with similar sizes can be interchangeable in size of suction, location of suction, discharge nozzles, baseplates, input shafts, foundation bolt holes, and mounting dimensions.

It is important to mention that alternate designs are considered by the standard, provided they meet its intent and cover construction and performance specifications in equivalence with those specified.

A review of ISO and ANSI pump standards

Energy savings from a European ISO product may just make it worth the effort. Please enter your name b773.1. Learn how your comment data is processed.

ANSI process pumps conform across manufacturers and allow the buyer to switch pumps and brands without having to change or redesign motor attachment, coupling, piping location, or bedplate dimensions. However, the design does not typically allow the pumps to move thicker liquids, such as oils. Additionally, these b7.31 set the guidelines and recommended practices related to the maintenance of these process pumps. All of this contributes to competitive markets and economic efficiency.
