Currently, we are facing a working condition involving a hydrochloric acid environment, with a flow rate that needs to be adjustable between 5 and 50 cubic meters per hour. Variable frequency drives can only be used to achieve this adjustment by changing the speed; the use of control valves is not permitted in this process. To ensure the required head pressure, attempts to select a centrifugal pump have failed time and again, which led us to turn to volumetric pumps instead.
