High-pressure pumps and compressors are machines to make high pressures and/or circulation in high-pressure unit operations. These machines are highly efficient for the respective application with the required pressure levels. For example, the turbomachines (centrifugal pumps and turbo-compressors 

A recirculating pump is a specialized device engineered to move liquids continuously within a closed-loop system. Unlike standard pumps that transfer liquids from one point to another, a recirculation pump operates within the same system, maintaining a steady flow without introducing new fluids

pressure pump is a centrifugal pump with a head of between 200 and 1200 m, which is used, for example, in pressure booster systems, Low-pressure, medium-pressure or super-pressure pumps are used for other areas of application.
