Pressure groups
They are sets intended for the supply of pressurized water for those facilities where a variable flow rate is required, such as in industrial processes. Normally, these units are made up of: an electric pump with a three-phase motor, a boiler, a pressure switch or a pressure transducer that gives a 4-20 mA signal to a variable speed drive, a pressure gauge, an impulsion manifold, a control cabinet. standard maneuver and a pump bench.
