What Are ANSI Pumps?
When it comes to industrial pumps, ASNI pumps have proven to be a versatile solution to chemical processing plants, wastewater treatment facilities, and more. But what exactly are ANSI pumps, and why are they so widely used in various industries?
What is an ANSI Pump?
An ANSI pump is a centrifugal pump that meets the standards of the American National Standards Institution (ANSI), which refers to standards for the dimensions of the pump. An ANSI pump is a horizontal, single-stage, and end-suction pump to allow for an efficient transfer of fluids.
Any manufacturer can create an ANSI pump with the requirements that it is dimensionally interchangeable regardless of brand or manufacturer. This makes servicing or finding parts for an ANSI pump easier than other pump types. And swapping ANSI pumps means not having to worry about reconfiguring a ton of things.
It’s not mandatory that all centrifugal pumps from manufacturers meet the ANSI standards, but organizations like the Occupational Safety and Health Administration (OSHA) will reference ANSI as a basis for their own standards.
What are ANSI Pumps Used For?
It’s common to see ANSI pumps used in industries that require moving fluids like water, alcohols, and other less aggressive fluids. Industries include:
- Chemical
- Food processing
- Pulp and paper
- Textiles
- Pharmaceuticals
- Ethanol production
- Water and wastewater
Depending on the impeller type, ANSI pumps can move fluids that contain solids but typically aren’t used for thicker or more viscous fluids.
ANSI vs. API Pumps
While ANSI pumps standards refer to the dimensions of the pump, making them interchangeable, standards set by the American Petroleum Institute (API) refer to the design of the pump’s construction and design. API pumps are built to handle more demanding conditions like high pressure, high temperatures, and emissions. This makes them ideal for oil refineries.
