Pumps are devices used to generate flow to move fluids and slurries from one point to another within a system. They vary widely in scope and function based on their design and mechanism. Selecting the right pump for an application requires an understanding and analysis of pump operation, components, performance specifications, features, and applications.

Every pump can be classified to some extent based on its mechanism or method of operation. For more information on these classifications and what they mean, see GlobalSpec's Pump Types page.
Pumps are made up of a variety of standard and nonstandard parts depending on their type and application. GlobalSpec's Pump Components page provides an overview of these different parts.
Understanding and interpreting performance specifications is a crucial part of correctly sourcing a pump for a specific system or application. For an overview of the most important pump specifications and what they mean, visit GlobalSpec's Pump Flow page.
Pumps may have a number of different features that add or enhance operation and functionality in a given application. Features include accessories, construction methods, materials, performance aspects, and power sources. GlobalSpec's Pump Features page contains a complete list and explanation of these different features.
A number of pump categories on GlobalSpec are organized based on pump application. Specifically, pumps can be classified based on a specific function they perform, or on the type of media that they handle. The Pump Applications page on GlobalSpec examines these different types of pumps.
Pump standards provide guidelines and consensus for the design and operation of pumping systems. A number of organizations provide these standards, some for specific industries or applications.
- American National Standards Institute (ANSI) / Hydraulic Institute (HI) – ANSI is a private non-profit organization that collects consensus standards on different types of products. HI creates product standards that define all aspects of pump products. In conjunction, ANSI/HI standards help manufacturers and purchasers make informed decisions on pump design to enhance performance.
- American Petroleum Institute (API) – API is the largest U.S. trade association for the oil and natural gas industry. They provide industry-specific standards for pumps in order to improve system efficiency and cost-effectiveness, comply with regulatory requirements, and ensure safety.
- ASTM International – Formerly known as the American Society for Testing and Materials, ASTM is a leading developer of international voluntary consensus standards. They provide a number of technical standards and specifications for different classifications of pumps.
- International Organization for Standardization (ISO) – ISO is the largest developer of voluntary international standards. They provide technical specifications and standards for numerous different types of pumps and components.
For definitions of commonly used terms used when dealing with pumps, see GlobalSpec's Pump Terminology page.
