Pumps & Parts

Industry Definition & Scope

The pumps and parts industry encompasses the design, manufacturing, distribution, and servicing of devices (pumps) and their components that move fluids (liquids, gases, or slurries) by mechanical action. This foundational industrial sector supports virtually every modern industry—from water supply and energy production to chemical processing and manufacturing—by providing critical fluid handling solutions. The industry combines mechanical engineering, material science, hydraulics, and increasingly, digital technologies to deliver efficient, reliable, and smart pumping systems.
