Many details need to be considered during the selection process, but it would be helpful to first understand the differences between ANSI and API pumps. Each of these pumps is designed according to different standards. API pumps are heavier duty and tend to operate more reliably under higher pressures, higher temperatures, and with the capacity to control emissions per EPA requirements. Typically more expensive than ANSI Pumps, API pumps have some major differences when it comes to the casing design, bearing housings, impellers, mounting, and back cover arrangements.
Much of this is covered in Heinz P. Budris, but below is a brief recap of some of these major differences. Impellers — manufactured without wear rings, ANSI pump impellers are open or semi-open; whereas API pumps feature closed impellers with replaceable casing wear rings. Bearing housings — the bearing housings of API pumps tend to be more robust steel design and often accommodate cooling jackets with greater capacity to handle higher temperatures than ANSI pumps.
Mounting — ANSI pumps are generally foot-mounted, which makes it hard to keep aligned at elevated and varying temperatures as thermal stresses can significantly decrease operational life. API pumps are centerline mounted to counter the effects of thermal expansion and minimize the amount of stress to the casing. Back Cover Arrangements — as pump expert Ross Mackay explains in slide 3 of his slideshare presentation 2, the back covers in each type of pump are secured differently.
In ANSI pumps, the back cover and gasket are held against the pump casing by a cast iron bearing frame adaptor; while in API pumps, the back cover is bolted directly to the casing and uses a compression gasket with metal-to-metal fits. When choosing a pump, the most important factor to consider is safety. Decisions on which type of pump to use must take into account not only the specific operating conditions and properties of the fluid being handled, but the safety and well-being of plant personnel and the surrounding environment.
We were one of the first American pump companies to attain ISO certification — the most recognized standard for quality in the world. So whether the job is refueling fighter jets on the deck of an aircraft carrier, supplying paint to an auto assembly line, or bringing water to the fountain in a city park, we put our reputation on the line everyday with every pump we build.
