The Complete Guide to ANSI Pumps from Rotech

ANSI Pumps are regulated centrifugal pumps. Centrifugal pumps are simple in construction and concept. ANSI Stands for American National Standards Institute, and ANSI Pumps are dimensionally regulated pumps. They are supposed to be horizontal, centreline discharge, and end single-stage suction. ANSI centrifugal pumps convert a motor’s mechanical energy into kinetic energy. This kinetic energy then turns into potential energy in the format of pumped fluid’s pressure which runs on a system curve with varying flow and head

ANSI pumps vary in dimension and size, regardless of the pump manufacturer. So, ANSI Process Pumps should meet the ANSI / ASME B73.1 standard of the American Society of Mechanical Engineers (ASME). These standards define the recommended practices and guidelines associated with the maintenance of these process pumps. The key focus area of this standard is that the equipment manufactured by all ANSI pump manufacturers should be interchangeable in regards to mounting dimensions, input shafts, discharge nozzles size and location of suction, input shafts, foundation bolt holes, and baseplates. The standard also considers alternate designs should they meet the standard’s intent and cover performance and construction-related specifications.

Applications of ANSI Pumps

Oil & Gas refineries, petrochemical, and chemical industries use ANSI chemical pumps. The other areas of application include paper stock, pharmaceutical, ethanol production, food processing, and many other process plants.

ANSI pumps most frequently get used for pumping thin fluids like alcohol, water, and other less aggressive fluids. ANSI pumps can pump fluids with solids based on the type of impeller. Furthermore, with proper material selection, ANSI pumps can transfer aggressive liquids that are highly corrosive.

Benefits of ANSI pumps

ANSI Pumps are flexible and readily available. They provide a reliable service for numerous applications, but these pumps are the most preferable for chemical processing. They introduce a great degree of ease and flexibility to the operations.

ANSI pumps are cost-effective and reliable. Plant operators can easily change these pumps without redesigning or changing motor attachment, baseplate dimensions, coupling, or piping.

Dimensional interchangeability across brands and manufacturers
High availability of ANSI parts and pumps
Higher affordability when compared to API pumps
With the right sort of impeller, ANSI pumps can pump fluids with solids in suspension
