Inline multi-stage pumps, also known as vertical multi-stage pumps, are a type of centrifugal pump designed for applications that require high-pressure water supply. These pumps consist of multiple impellers stacked together in a single casing, allowing them to generate higher pressure than single-stage pumps.
