Your Guide to ANSI Process Pumps
Centrifugal ANSI process pumps are a dependable workhorse for many operations and applications. Regulated by the American National Standards Institute (ANSI), these particular pumps have to meet specific dimensional standards. With strict regulations, it’s easy to interchange pumps when one breaks down; however, ANSI process pumps do have their limitations.
We’ve put together this quick guide to help you understand the pros and cons of ANSI process pumps, the applications they’re best suited for and the specific pumps we recommend.
What Are ANSI Process Pumps?
ANSI Process pumps are a dimensionally regulated type of centrifugal pump. These pumps are horizontal, end suction, single-stage pumps. All ANSI process pumps are similar in size and identical in interface. With these regulations in place, it’s easy to swap out pumps as needed.
While the sizes and interfaces are specifically defined, there are many ANSI process pump features that vary by manufacturer. For example, some ANSI process pumps can be manufactured using specific materials to handle corrosive liquids.
There are three main groups of ANSI process pump, based on size:
- Group I. Sizes from 1.5 by 1-6 to 3.0 by 1.5-8
- Group II. Sizes from 3 by 2-8 to 6 by 4-13
- Group III. Sizes from 6 by 4-16 to 10 by 8-17
Applications for ANSI Process Pumps
Typically, ANSI process pumps are used for applications that require transferring water and thin liquids. Centrifugal pumps are usually not the best choice for thicker liquids and oils. Likewise, some ANSI process pumps are capable of pumping liquids containing solids. Be sure to verify with an expert or manufacturer before purchasing an ANSI process pump to be sure it’s compatible with your operation.
ANSI process pumps only meet one standard and may not be the best choice for all centrifugal pump applications. If you’re unsure when choosing an ANSI process pump for your application, our pump experts can make a recommendation for you.
The chemical industry is the primary user of ANSI process pumps. Additionally, food processing, paper mills, pulp mills, refineries, ethanol production, textiles and various other process plant applications depend on these pumps.
