However, there has been a degree of convergence as the two standards bodies borrow from each other. Dimensions include overall height and length of the bare pump, nozzle and shaft diameters, the size, location and spacing of mounting bolts, etc. 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 anis standards.

This article will focus on a comparison of two important sets of standards for industrial pumps: The plugin only becomes active when you click the button, which indicates that you agree to communicate with the social network.

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

Saving energy efficiently December 27, Standards are an extremely important part of the industrial and commercial landscape. Industry Person of the Week — Nadine Znsi.

Pumps must meet dimensional interchangeability requirements and contain special features for installation and maintenance. All of this contributes to competitive markets and economic efficiency.

Ruhrpumpen ANSI / ASME B Process Pump Range

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. In addition, ANSI pumps only meet one standard so they are difficult or not feasible as replacements for other types of centrifugal pumps. Learn how your comment data is processed. By 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.

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. This pump comes in a wide range of materials, including alloys and non-metals for many corrosive services, depending on the application.

The pumps can also move liquids with or without solids based on their impeller type.

Introducing the RP ANSI Process Pump Range

In some aspects e. By specifying standards-compliant products, buyers can be assured that the items they acquire will meet important performance and safety requirements, even if amsi come from companies that the buyers have never dealt with before. The total head pressure ranges from 50 to feet 22 to psiand horsepower from 1.

Even though ANSI chemical znsi they are mostly ansu in the chemical and petrochemical industries, they can also be found in paper stock, ethanol production, pharmaceutical, food processing and several other process plants. 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. Since then, the committee has continued to be anssi and has defined the standards for 27 pump sizes through several revisions.

Energy savings from a European ISO product may just make it worth the effort. Go to subscribe form No, thank you. Empowering Pumps is the information and connection hub for the global pump industry.

It is the specification for horizontal, end suction, single stage aansi pumps for chemical process applications, and covers metallic centrifugal pump designs. All operating manuals, type series booklets, characteristic curves, typical tenders, product brochures and corporate publications.

Sincecommittees in the United States have worked on the development of centrifugal pump standards to meet the needs of the chemical industry.

Subscribe to RPConnect, our digital monthly newsletter. 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.

This site uses Akismet to reduce spam. There are now more than 19, international standards covering many aspects of technology and business. Additionally, these standards set the guidelines and recommended practices related to the maintenance of these process pumps. By definition, these chemical pumps are anssi, end suction single stage, centerline discharge, centrifugal pumps comparable in size and dimensions regardless of pump manufacturer.

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 ANSI process pump sizing standard is broken down into three main groups. 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 standard was developed to address the needs of the chemical industry for a robust family of single-stage end-suction centrifugal pumps.
