The concept of centrifugal pumps dates back to the 17th century, but their widespread industrial adoption began during the 19th and 20th centuries with the growth of factories, water distribution networks, and oil refineries. Today, they are essential in water treatment, agriculture, chemical processing, HVAC systems, energy production, and countless other fields.
Centrifugal pumps exist because industries and households need a reliable, efficient, and scalable method of moving fluids. Unlike positive displacement pumps, which push fixed volumes of liquid, centrifugal pumps provide smooth, continuous flow with relatively low maintenance needs.
